			&quot;<A HREF="#dl">dl</A>&quot;.

			See |<A HREF="options.html#:fixdel">:fixdel</A>| if the <A HREF="#&lt;Del&gt;">&lt;Del&gt;</A> key does not <A HREF="diff.html#do">do</A> what you

{Visual}[&quot;x]x	or					*<A NAME="v_x"></A><B>v_x</B>* *<A NAME="v_d"></A><B>v_d</B>* *<A NAME="v_&lt;Del&gt;"></A><B>v_&lt;Del&gt;</B>*
{Visual}[&quot;x]d   or

			<A HREF="intro.html#{Visual}">{Visual}</A> see |<A HREF="visual.html#Visual-mode">Visual-mode</A>|).  In Visual block mode,
			&quot;<A HREF="#D">D</A>&quot; deletes the highlighted text plus all text until

					*<A NAME=":d"></A><B>:d</B>* *<A NAME=":de"></A><B>:de</B>* *<A NAME=":del"></A><B>:del</B>* *<A NAME=":delete"></A><B>:delete</B>* *<A NAME=":dl"></A><B>:dl</B>* *<A NAME=":dp"></A><B>:dp</B>*
:[range]d[elete] [x]	Delete <A HREF="cmdline.html#[range]">[range]</A> lines (default: current line) [into
			<A HREF="sponsor.html#register">register</A> x].
			Note these weird <A HREF="map.html#abbreviations">abbreviations</A>:
			   <A HREF="#:dl">:dl</A>		delete and <A HREF="eval.html#list">list</A>
			   :dell	idem

			   :dep		idem
			   :delp	idem
			   :delep	idem
			   :deletp	idem
			   :deletep	idem

:[range]d[elete] [x] {count}
			Delete {count} lines, starting with <A HREF="cmdline.html#[range]">[range]</A>
			(default: current line |<A HREF="cmdline.html#cmdline-ranges">cmdline-ranges</A>|) [into
			<A HREF="sponsor.html#register">register</A> x].

These commands delete text.  You can repeat them with the `.` command
(except `:d`) and <A HREF="undo.html#undo">undo</A> them.  Use <A HREF="visual.html#Visual">Visual</A> mode to delete blocks of text.  See
|<A HREF="#registers">registers</A>| for an explanation of registers.

An exception for the d{motion} command: If the motion is not <A HREF="motion.html#linewise">linewise</A>, the
start and end of the motion are not in the same line, and there are only
blanks before the start and there are no non-blanks after the end of the
motion, the delete becomes <A HREF="motion.html#linewise">linewise</A>.  This means that the delete also removes
the line of blanks that you might expect to remain. Use the |<A HREF="motion.html#o_v">o_v</A>| <A HREF="motion.html#operator">operator</A> to
force the motion to be <A HREF="motion.html#characterwise">characterwise</A>.

Trying to delete an empty region of text (e.g., &quot;d0&quot; in the first column)
is an error when <A HREF="options.html#'cpoptions'">'cpoptions'</A> includes the '<A HREF="motion.html#E">E</A>' flag.


							*<A NAME="J"></A><B>J</B>*
<A HREF="#J">J</A>			Join <A HREF="intro.html#[count]">[count]</A> lines, with a minimum of two lines.
			Remove the indent and insert up to two spaces (see
			below).  Fails when on the last line of the buffer.
			If <A HREF="intro.html#[count]">[count]</A> is too big <A HREF="motion.html#it">it</A> is reduce to the number of
			lines available.

			the join does not insert or delete any spaces.
			If a <A HREF="cmdline.html#[range]">[range]</A> has equal start and end values, this

These commands delete the <A HREF="intro.html#&lt;EOL&gt;">&lt;EOL&gt;</A> between lines.  This has the effect of joining
multiple lines into one line.  You can repeat these commands (except `:j`) and
<A HREF="undo.html#undo">undo</A> them.

These commands, except &quot;<A HREF="#gJ">gJ</A>&quot;, insert one space in place of the <A HREF="intro.html#&lt;EOL&gt;">&lt;EOL&gt;</A> unless
there is trailing white space or the next line starts with a '<A HREF="motion.html#)">)</A>'.  These
commands, except &quot;<A HREF="#gJ">gJ</A>&quot;, delete any leading white space on the next line.  If
the <A HREF="options.html#'joinspaces'">'joinspaces'</A> option is on, these commands insert two spaces after a '<A HREF="repeat.html#.">.</A>',
'<A HREF="#!">!</A>' or '<A HREF="pattern.html#?">?</A>' (but if <A HREF="options.html#'cpoptions'">'cpoptions'</A> includes the '<A HREF="motion.html#j">j</A>' flag, they insert two spaces
only after a '.').
The '<A HREF="motion.html#B">B</A>' and '<A HREF="motion.html#M">M</A>' flags in <A HREF="options.html#'formatoptions'">'formatoptions'</A> change the behavior for <A HREF="insert.html#inserting">inserting</A>
spaces before and after a <A HREF="mbyte.html#multi-byte">multi-byte</A> character |<A HREF="#fo-table">fo-table</A>|.

Notes:
- You can end <A HREF="insert.html#Insert">Insert</A> and <A HREF="insert.html#Replace">Replace</A> mode with <A HREF="intro.html#&lt;Esc&gt;">&lt;Esc&gt;</A>.
- See the section &quot;<A HREF="insert.html#Insert">Insert</A> and <A HREF="insert.html#Replace">Replace</A> mode&quot; |<A HREF="insert.html#mode-ins-repl">mode-ins-repl</A>| for the other
  special characters in these modes.
- The effect of <A HREF="intro.html#[count]">[count]</A> takes place after Vim exits <A HREF="insert.html#Insert">Insert</A> or <A HREF="insert.html#Replace">Replace</A> mode.
- When the <A HREF="options.html#'cpoptions'">'cpoptions'</A> option contains '<A HREF="motion.html#$">$</A>' and the change is within one line,
  Vim continues to show the text to be deleted and puts a '<A HREF="motion.html#$">$</A>' at the last
  deleted character.

See |<A HREF="#registers">registers</A>| for an explanation of registers.

<A HREF="insert.html#Replace">Replace</A> mode is just like <A HREF="insert.html#Insert">Insert</A> mode, except that every character you enter
deletes one character.  If you reach the end of a line, Vim appends any
further characters (just like <A HREF="insert.html#Insert">Insert</A> mode).  In <A HREF="insert.html#Replace">Replace</A> mode, the backspace
key restores the original text (if there was any).  (See section &quot;<A HREF="insert.html#Insert">Insert</A> and
<A HREF="insert.html#Replace">Replace</A> mode&quot; |<A HREF="insert.html#mode-ins-repl">mode-ins-repl</A>|).

white space after a <A HREF="motion.html#word">word</A>, they only change up to the end of the <A HREF="motion.html#word">word</A>.  This is
because Vim interprets &quot;<A HREF="#cw">cw</A>&quot; <A HREF="motion.html#as">as</A> change-word, and a <A HREF="motion.html#word">word</A> does not include the
following white space.
{Vi: &quot;<A HREF="#cw">cw</A>&quot; when on a blank followed by other blanks changes only the first
blank; this is probably a bug, because &quot;dw&quot; deletes all the blanks; use the
'<A HREF="motion.html#w">w</A>' flag in <A HREF="options.html#'cpoptions'">'cpoptions'</A> to make <A HREF="motion.html#it">it</A> work like <A HREF="intro.html#Vi">Vi</A> anyway}

If you prefer &quot;<A HREF="#cw">cw</A>&quot; to include the space after a <A HREF="motion.html#word">word</A>, use this <A HREF="map.html#mapping">mapping</A>:
<B>	:map cw dwi</B>
Or use &quot;caw&quot; (see |<A HREF="motion.html#aw">aw</A>|).

			Type a line containing only &quot;<A HREF="repeat.html#.">.</A>&quot; to stop <A HREF="#replacing">replacing</A>.
			Without {range}, this command changes only the current

3. Simple changes					*<A NAME="simple-change"></A><B>simple-change</B>*


							*<A NAME="r"></A><B>r</B>*
r{char}			<A HREF="insert.html#Replace">Replace</A> the character under the cursor with {char}.
			If {char} is a <A HREF="motion.html#&lt;CR&gt;">&lt;CR&gt;</A> or <A HREF="motion.html#&lt;NL&gt;">&lt;NL&gt;</A>, a line break replaces the
			character.  To replace with a real <A HREF="motion.html#&lt;CR&gt;">&lt;CR&gt;</A>, use <A HREF="visual.html#CTRL-V">CTRL-V</A>
			<A HREF="motion.html#&lt;CR&gt;">&lt;CR&gt;</A>.  <A HREF="visual.html#CTRL-V">CTRL-V</A> <A HREF="motion.html#&lt;NL&gt;">&lt;NL&gt;</A> replaces with a <A HREF="intro.html#&lt;Nul&gt;">&lt;Nul&gt;</A>.
			{Vi: <A HREF="visual.html#CTRL-V">CTRL-V</A> <A HREF="motion.html#&lt;CR&gt;">&lt;CR&gt;</A> still replaces with a line break,
			cannot replace something with a &lt;CR&gt;}

			If {char} is <A HREF="scroll.html#CTRL-E">CTRL-E</A> or <A HREF="scroll.html#CTRL-Y">CTRL-Y</A> the character from the
			line below or above is used, just like with |<A HREF="insert.html#i_CTRL-E">i_CTRL-E</A>|
			and |<A HREF="insert.html#i_CTRL-Y">i_CTRL-Y</A>|.  This also works with a <A HREF="intro.html#count">count</A>, thus
			`10r&lt;C-E&gt;` copies 10 characters from the line below.

			If you give a <A HREF="intro.html#[count]">[count]</A>, Vim replaces <A HREF="intro.html#[count]">[count]</A> characters
			with <A HREF="intro.html#[count]">[count]</A> {char}s.  When {char} is a <A HREF="motion.html#&lt;CR&gt;">&lt;CR&gt;</A> or <A HREF="motion.html#&lt;NL&gt;">&lt;NL&gt;</A>,
			however, Vim inserts only one <A HREF="motion.html#&lt;CR&gt;">&lt;CR&gt;</A>: &quot;5r&lt;CR&gt;&quot; replaces
			five characters with a single line break.
			When {char} is a <A HREF="motion.html#&lt;CR&gt;">&lt;CR&gt;</A> or <A HREF="motion.html#&lt;NL&gt;">&lt;NL&gt;</A>, Vim performs
			autoindenting.  This works just like <A HREF="#deleting">deleting</A> the
			characters that are replaced and then doing
			&quot;i&lt;CR&gt;&lt;Esc&gt;&quot;.
			{char} can be entered <A HREF="motion.html#as">as</A> a digraph |<A HREF="#digraph-arg">digraph-arg</A>|.
			|<A HREF="map.html#:lmap">:lmap</A>| mappings apply to {char}.  The <A HREF="editing.html#CTRL-^">CTRL-^</A> command
			in <A HREF="insert.html#Insert">Insert</A> mode can be used to switch this on/off
			|<A HREF="insert.html#i_CTRL-^">i_CTRL-^</A>|.  See |<A HREF="mbyte.html#utf-8-char-arg">utf-8-char-arg</A>| about using
			composing characters when <A HREF="options.html#'encoding'">'encoding'</A> is <A HREF="mbyte.html#Unicode">Unicode</A>.


							*<A NAME="gr"></A><B>gr</B>*
gr{char}		<A HREF="insert.html#Replace">Replace</A> the virtual characters under the cursor with
			{char}.  This replaces in screen space, not file
			space.  See |<A HREF="#gR">gR</A>| and |<A HREF="insert.html#Virtual-Replace-mode">Virtual-Replace-mode</A>| for more
			details.  As with |<A HREF="#r">r</A>| a <A HREF="intro.html#count">count</A> may be given.
			{char} can be entered like with |<A HREF="#r">r</A>|.
			{not available when compiled without the |<A HREF="various.html#+vreplace">+vreplace</A>|

						*<A NAME="digraph-arg"></A><B>digraph-arg</B>*
The argument for <A HREF="intro.html#Normal">Normal</A> mode commands like |<A HREF="#r">r</A>| and |<A HREF="motion.html#t">t</A>| is a single character.
When <A HREF="options.html#'cpo'">'cpo'</A> doesn't contain the '<A HREF="#D">D</A>' flag, this character can also be entered
like |<A HREF="digraph.html#digraphs">digraphs</A>|.  First type CTRL-K and then the two digraph characters.
{not available when compiled without the |<A HREF="various.html#+digraphs">+digraphs</A>| feature}


						*<A NAME="case"></A><B>case</B>*
The following commands change the <A HREF="#case">case</A> of letters.  The currently active
|<A HREF="mbyte.html#locale">locale</A>| is used.  See |<A HREF="mlang.html#:language">:language</A>|.  The LC_CTYPE value matters here.


							*<A NAME="~"></A><B>~</B>*
~			<A HREF="options.html#'notildeop'">'notildeop'</A> option: Switch <A HREF="#case">case</A> of the character

gU{motion}		Make <A HREF="intro.html#{motion}">{motion}</A> text <A HREF="#uppercase">uppercase</A>. {not in Vi}
			Example:
<B>				:map! &lt;C-F&gt; &lt;Esc&gt;gUiw`]a</B>
 			This works in <A HREF="insert.html#Insert">Insert</A> mode: press <A HREF="scroll.html#CTRL-F">CTRL-F</A> to make the
			<A HREF="motion.html#word">word</A> before the cursor <A HREF="#uppercase">uppercase</A>.  Handy to type

The <A HREF="#CTRL-A">CTRL-A</A> and <A HREF="#CTRL-X">CTRL-X</A> commands can work for:
- signed and unsigned decimal numbers

This depends on the <A HREF="options.html#'nrformats'">'nrformats'</A> option:
- When <A HREF="options.html#'nrformats'">'nrformats'</A> includes &quot;bin&quot;, Vim assumes numbers starting with '0b' or
  '0B' are binary.
- When <A HREF="options.html#'nrformats'">'nrformats'</A> includes &quot;<A HREF="eval.html#octal">octal</A>&quot;, Vim considers numbers starting with a '<A HREF="motion.html#0">0</A>'
  to be <A HREF="eval.html#octal">octal</A>, unless the number includes a '8' or '9'.  Other numbers are
  decimal and may have a preceding minus sign.
  If the cursor is on a number, the commands apply to that number; otherwise
  Vim uses the number to the right of the cursor.
- When <A HREF="options.html#'nrformats'">'nrformats'</A> includes &quot;hex&quot;, Vim assumes numbers starting with '0x' or
  '0X' are hexadecimal.  The <A HREF="#case">case</A> of the rightmost <A HREF="print.html#letter">letter</A> in the number
  determines the <A HREF="#case">case</A> of the resulting hexadecimal number.  If there is no
  <A HREF="print.html#letter">letter</A> in the current number, Vim uses the previously detected <A HREF="#case">case</A>.
- When <A HREF="options.html#'nrformats'">'nrformats'</A> includes &quot;alpha&quot;, Vim will change the alphabetic character
  under or after the cursor.  This is useful to make lists with an alphabetic
  index.

For decimals a leading negative sign is considered for incrementing/
decrementing, for binary, <A HREF="eval.html#octal">octal</A> and hex values, <A HREF="motion.html#it">it</A> won't be considered.  To
ignore the sign Visually select the number before using <A HREF="#CTRL-A">CTRL-A</A> or <A HREF="#CTRL-X">CTRL-X</A>. 

For numbers with leading zeros (including all <A HREF="eval.html#octal">octal</A> and hexadecimal numbers),
Vim preserves the number of characters in the number when possible.  <A HREF="#CTRL-A">CTRL-A</A> on
&quot;0077&quot; results in &quot;0100&quot;, <A HREF="#CTRL-X">CTRL-X</A> on &quot;0x100&quot; results in &quot;0x0ff&quot;.
There is one exception: When a number that starts with a zero is found not to
be <A HREF="eval.html#octal">octal</A> (it contains a '8' or '9'), but <A HREF="options.html#'nrformats'">'nrformats'</A> does include &quot;<A HREF="eval.html#octal">octal</A>&quot;,
leading zeros are removed to avoid that the result may be recognized <A HREF="motion.html#as">as</A> an
<A HREF="eval.html#octal">octal</A> number.

Note that when <A HREF="options.html#'nrformats'">'nrformats'</A> includes &quot;<A HREF="eval.html#octal">octal</A>&quot;, decimal numbers with leading
zeros cause mistakes, because they can be confused with <A HREF="eval.html#octal">octal</A> numbers.

Note similarly, when <A HREF="options.html#'nrformats'">'nrformats'</A> includes &quot;bin&quot;, binary numbers with a leading
'0x' or '0X' can be interpreted <A HREF="motion.html#as">as</A> hexadecimal rather than binary since '0b'
are valid hexadecimal digits.

The <A HREF="#CTRL-A">CTRL-A</A> command is very useful in a <A HREF="map.html#macro">macro</A>.  Example: Use the following
steps to make a numbered <A HREF="eval.html#list">list</A>.

1. Create the first <A HREF="eval.html#list">list</A> entry, make sure <A HREF="motion.html#it">it</A> starts with a number.
2. qa	     - start <A HREF="repeat.html#recording">recording</A> into <A HREF="sponsor.html#register">register</A> '<A HREF="insert.html#a">a</A>'
3. <A HREF="#Y">Y</A>	     - <A HREF="#yank">yank</A> the entry
4. <A HREF="#p">p</A>	     - put a copy of the entry below the first one
5. <A HREF="#CTRL-A">CTRL-A</A>    - increment the number
6. <A HREF="repeat.html#q">q</A>	     - stop <A HREF="repeat.html#recording">recording</A>
7. &lt;count&gt;@a - repeat the <A HREF="#yank">yank</A>, put and increment <A HREF="map.html#&lt;count&gt;">&lt;count&gt;</A> times

			Repeat '<A HREF="#&gt;">&gt;</A>' for shifting multiple 'shiftwidth's.
			See |<A HREF="cmdline.html#ex-flags">ex-flags</A>| for [flags].

The &quot;<A HREF="#&gt;">&gt;</A>&quot; and &quot;<A HREF="#&lt;">&lt;</A>&quot; commands are handy for <A HREF="#changing">changing</A> the indentation within
programs.  Use the <A HREF="options.html#'shiftwidth'">'shiftwidth'</A> option to set the size of the white space
which these commands insert or delete.  Normally the <A HREF="options.html#'shiftwidth'">'shiftwidth'</A> option is 8,
but you can set <A HREF="motion.html#it">it</A> to, say, 3 to make smaller indents.  The <A HREF="intro.html#shift">shift</A> leftwards
stops when there is no indent.  The <A HREF="intro.html#shift">shift</A> right does not affect empty lines.

If the <A HREF="options.html#'shiftround'">'shiftround'</A> option is on, the indent is rounded to a multiple of
<A HREF="options.html#'shiftwidth'">'shiftwidth'</A>.

If the <A HREF="options.html#'smartindent'">'smartindent'</A> option is on, or <A HREF="options.html#'cindent'">'cindent'</A> is on and <A HREF="options.html#'cinkeys'">'cinkeys'</A> contains
'<A HREF="pattern.html##">#</A>' with a zero value, <A HREF="intro.html#shift">shift</A> right does not affect lines starting with '<A HREF="pattern.html##">#</A>'
(these are supposed to be C preprocessor lines that must stay in column 1).

When the <A HREF="options.html#'expandtab'">'expandtab'</A> option is off (this is the default) Vim uses &lt;Tab&gt;s <A HREF="motion.html#as">as</A>
much <A HREF="motion.html#as">as</A> possible to make the indent.  You can use &quot;&gt;&gt;&lt;&lt;&quot; to replace an indent
made out of spaces with the same indent made out of &lt;Tab&gt;s (and a few spaces
if necessary).  If the <A HREF="options.html#'expandtab'">'expandtab'</A> option is on, Vim uses only spaces.  Then
you can use &quot;&gt;&gt;&lt;&lt;&quot; to replace &lt;Tab&gt;s in the indent by spaces (or use
`:retab!`).

To move a line several 'shiftwidth's, use <A HREF="visual.html#Visual">Visual</A> mode or the `:` commands.
For example:
<B>	Vjj4&gt;		move three lines 4 indents to the right</B>
<B>	:&lt;&lt;&lt;		move current line 3 indents to the left</B>
<B>	:&gt;&gt; 5		move 5 lines 2 indents to the right</B>
<B>	:5&gt;&gt;		move line 5 2 indents to the right</B>

4. Complex changes					*<A NAME="complex-change"></A><B>complex-change</B>*


4.1 Filter commands					*<A NAME="filter"></A><B>filter</B>*

A <A HREF="#filter">filter</A> is a program that accepts text at standard input, changes <A HREF="motion.html#it">it</A> in some
way, and sends <A HREF="motion.html#it">it</A> to standard output.  You can use the commands below to send
some text through a <A HREF="#filter">filter</A>, so that <A HREF="motion.html#it">it</A> is replaced by the <A HREF="#filter">filter</A> output.
Examples of filters are &quot;sort&quot;, which sorts lines alphabetically, and
&quot;indent&quot;, which formats C program files (you need a version of indent that
works like a <A HREF="#filter">filter</A>; not all versions <A HREF="diff.html#do">do</A>).  The <A HREF="options.html#'shell'">'shell'</A> option specifies the
shell Vim uses to execute the <A HREF="#filter">filter</A> command (See also the <A HREF="options.html#'shelltype'">'shelltype'</A>
option).  You can repeat <A HREF="#filter">filter</A> commands with &quot;<A HREF="repeat.html#.">.</A>&quot;.  Vim does not recognize a
comment (starting with &#39;&#34;'') after the `:!` command.


							*<A NAME="!"></A><B>!</B>*
!{motion}{filter}	Filter <A HREF="intro.html#{motion}">{motion}</A> text lines through the external
			program {filter}.


							*<A NAME="!!"></A><B>!!</B>*
!!{filter}		Filter <A HREF="intro.html#[count]">[count]</A> lines through the external program
			{filter}.


							*<A NAME="v_!"></A><B>v_!</B>*
{Visual}!{filter}	Filter the highlighted lines through the external
			program {filter} (for <A HREF="intro.html#{Visual}">{Visual}</A> see |<A HREF="visual.html#Visual-mode">Visual-mode</A>|).
			{not in Vi}


:{range}![!]{filter} [!][arg]				*<A NAME=":range!"></A><B>:range!</B>*
			Filter {range} lines through the external program
			{filter}.  Vim replaces the optional bangs with the
			latest given command and appends the optional [arg].
			Vim saves the output of the <A HREF="#filter">filter</A> command in a
			temporary file and then reads the file into the buffer
			|<A HREF="#tempfile">tempfile</A>|.  Vim uses the <A HREF="options.html#'shellredir'">'shellredir'</A> option to
			redirect the <A HREF="#filter">filter</A> output to the temporary file.
			However, if the <A HREF="options.html#'shelltemp'">'shelltemp'</A> option is off then pipes
			are used when possible (on <A HREF="os_unix.html#Unix">Unix</A>).
			When the '<A HREF="#R">R</A>' flag is included in <A HREF="options.html#'cpoptions'">'cpoptions'</A> marks in
			the filtered lines are deleted, unless the
			|<A HREF="motion.html#:keepmarks">:keepmarks</A>| command is used.  Example:
<B>				:keepmarks '&lt;,'&gt;!sort</B>
 			When the number of lines after filtering is <A HREF="various.html#less">less</A> than
			before, marks in the missing lines are deleted anyway.


							*<A NAME="="></A><B>=</B>*
={motion}		Filter <A HREF="intro.html#{motion}">{motion}</A> lines through the external program
			given with the <A HREF="options.html#'equalprg'">'equalprg'</A> option.  When the <A HREF="options.html#'equalprg'">'equalprg'</A>
			option is empty (this is the default), use the
			internal <A HREF="#formatting">formatting</A> function |<A HREF="indent.html#C-indenting">C-indenting</A>| and
			|<A HREF="options.html#'lisp'">'lisp'</A>|.  But when <A HREF="options.html#'indentexpr'">'indentexpr'</A> is not empty, <A HREF="motion.html#it">it</A> will
			be used instead |<A HREF="indent.html#indent-expression">indent-expression</A>|.  When Vim was
			compiled without internal <A HREF="#formatting">formatting</A> then the &quot;indent&quot;
			program is used <A HREF="motion.html#as">as</A> a last resort.


							*<A NAME="=="></A><B>==</B>*
<A HREF="#==">==</A>			Filter <A HREF="intro.html#[count]">[count]</A> lines like with ={motion}.


							*<A NAME="v_="></A><B>v_=</B>*
{Visual}=		Filter the highlighted lines like with ={motion}.
			{not in Vi}



						*<A NAME="tempfile"></A><B>tempfile</B>* *<A NAME="setuid"></A><B>setuid</B>*
Vim uses temporary files for filtering, generating diffs and also for
<A HREF="eval.html#tempname()">tempname()</A>.  For <A HREF="os_unix.html#Unix">Unix</A>, the file will be in a private directory (only
accessible by the current user) to avoid security problems (e.g., a symlink
attack or other people reading your file).  When Vim exits the directory and
all files in <A HREF="motion.html#it">it</A> are deleted.  When Vim has the <A HREF="#setuid">setuid</A> bit set this may cause
problems, the temp file is owned by the <A HREF="#setuid">setuid</A> user but the <A HREF="#filter">filter</A> command
probably runs <A HREF="motion.html#as">as</A> the original user.
On <A HREF="os_msdos.html#MS-DOS">MS-DOS</A> and <A HREF="os_os2.html#OS/2">OS/2</A> the first of these directories that works is used: $TMP,
$TEMP, c:\TMP, c:\TEMP.
For <A HREF="os_unix.html#Unix">Unix</A> the <A HREF="eval.html#list">list</A> of directories is: $TMPDIR, /tmp, current-dir, <A HREF="options.html#$HOME">$HOME</A>.
For <A HREF="os_win32.html#MS-Windows">MS-Windows</A> the GetTempFileName() system function is used.
For other systems the tmpnam() library function is used.




4.2 Substitute						*<A NAME=":substitute"></A><B>:substitute</B>*

							*<A NAME=":s"></A><B>:s</B>* *<A NAME=":su"></A><B>:su</B>*
:[range]s[ubstitute]/{pattern}/{string}/[flags] <A HREF="intro.html#[count]">[count]</A>
			For each line in <A HREF="cmdline.html#[range]">[range]</A> replace a match of {pattern}
			with {string}.
			For the {pattern} see |<A HREF="pattern.html#pattern">pattern</A>|.
			{string} can be a literal <A HREF="eval.html#string">string</A>, or something
			special; see |<A HREF="#sub-replace-special">sub-replace-special</A>|.

							*<A NAME="E939"></A><B>E939</B>*
			When <A HREF="cmdline.html#[range]">[range]</A> and <A HREF="intro.html#[count]">[count]</A> are omitted, replace in the
			current line only.  When <A HREF="intro.html#[count]">[count]</A> is given, replace in
			<A HREF="intro.html#[count]">[count]</A> lines, starting with the last line in <A HREF="cmdline.html#[range]">[range]</A>.
			When <A HREF="cmdline.html#[range]">[range]</A> is omitted start in the current line.
			<A HREF="intro.html#[count]">[count]</A> must be a positive number.  Also see
			|<A HREF="cmdline.html#cmdline-ranges">cmdline-ranges</A>|.

			See |<A HREF="#:s_flags">:s_flags</A>| for [flags].

:[range]s[ubstitute] [flags] <A HREF="intro.html#[count]">[count]</A>

:[range]&amp;[&amp;][flags] <A HREF="intro.html#[count]">[count]</A>					*<A NAME=":&amp;"></A><B>:&amp;</B>*
			Repeat last <A HREF="#:substitute">:substitute</A> with same search <A HREF="pattern.html#pattern">pattern</A> and
			substitute <A HREF="eval.html#string">string</A>, but without the same flags.  You
			may add [flags], see |<A HREF="#:s_flags">:s_flags</A>|.
			Note that after `:substitute` the '<A HREF="#&amp;">&amp;</A>' flag can't be
			used, it's recognized <A HREF="motion.html#as">as</A> a <A HREF="pattern.html#pattern">pattern</A> separator.
			The space between `:substitute` and the '<A HREF="#c">c</A>', '<A HREF="index.html#g">g</A>',
			'<A HREF="insert.html#i">i</A>', '<A HREF="insert.html#I">I</A>' and '<A HREF="#r">r</A>' flags isn't required, but in scripts
			it's a good idea to keep <A HREF="motion.html#it">it</A> to avoid confusion.


:[range]~[&amp;][flags] <A HREF="intro.html#[count]">[count]</A>					*<A NAME=":~"></A><B>:~</B>*
			Repeat last substitute with same substitute <A HREF="eval.html#string">string</A>
			but with last used search <A HREF="pattern.html#pattern">pattern</A>.  This is like
			`:&amp;r`.  See |<A HREF="#:s_flags">:s_flags</A>| for [flags].


								*<A NAME="&amp;"></A><B>&amp;</B>*
<A HREF="#&amp;">&amp;</A>			Synonym for `:s` (repeat last substitute).  Note
			that the flags are not remembered, thus <A HREF="motion.html#it">it</A> might
			actually work differently.  You can use `:&amp;&amp;` to keep
			the flags.


								*<A NAME="g&amp;"></A><B>g&amp;</B>*
<A HREF="#g&amp;">g&amp;</A>			Synonym for `:&#37;s//~/&amp;` (repeat last substitute with
			last search <A HREF="pattern.html#pattern">pattern</A> on all lines with the same flags).
			For example, when you first <A HREF="diff.html#do">do</A> a substitution with
			`:s/pattern/repl/flags` and then `/search` for
			something else, `g&amp;` will <A HREF="diff.html#do">do</A> `:&#37;s/search/repl/flags`.
			Mnemonic: global substitute. {not in Vi}


						*<A NAME=":snomagic"></A><B>:snomagic</B>* *<A NAME=":sno"></A><B>:sno</B>*
:[range]sno[magic] <A HREF="eval.html#...">...</A>	Same <A HREF="motion.html#as">as</A> `:substitute`, but always use <A HREF="options.html#'nomagic'">'nomagic'</A>.

			{not in Vi}


							*<A NAME=":s_flags"></A><B>:s_flags</B>*
The flags that you can use for the substitute commands:


							*<A NAME=":&amp;&amp;"></A><B>:&amp;&amp;</B>*
[&amp;]	Must be the first one: Keep the flags from the previous substitute
	command.  Examples:
<B>		:&amp;&amp;</B>
<B>		:s/this/that/&amp;</B>
 	Note that `:s` and `:&amp;` don't keep the flags.
	{not in Vi}

[c]	Confirm each substitution.  Vim highlights the matching <A HREF="eval.html#string">string</A> (with

	|<A HREF="syntax.html#hl-IncSearch">hl-IncSearch</A>|).  You can type:				*<A NAME=":s_c"></A><B>:s_c</B>*
	    '<A HREF="#y">y</A>'	    to substitute this match
	    '<A HREF="motion.html#l">l</A>'	    to substitute this match and then quit (&quot;last&quot;)
	    '<A HREF="pattern.html#n">n</A>'	    to skip this match
	    <A HREF="intro.html#&lt;Esc&gt;">&lt;Esc&gt;</A>   to quit substituting
	    '<A HREF="insert.html#a">a</A>'	    to substitute this and all remaining matches {not in Vi}
	    '<A HREF="repeat.html#q">q</A>'	    to quit substituting {not in Vi}
	    <A HREF="scroll.html#CTRL-E">CTRL-E</A>  to scroll the screen up {not in <A HREF="intro.html#Vi">Vi</A>, not available when
			compiled without the |<A HREF="various.html#+insert_expand">+insert_expand</A>| feature}
	    <A HREF="scroll.html#CTRL-Y">CTRL-Y</A>  to scroll the screen down {not in <A HREF="intro.html#Vi">Vi</A>, not available when
			compiled without the |<A HREF="various.html#+insert_expand">+insert_expand</A>| feature}
	If the <A HREF="options.html#'edcompatible'">'edcompatible'</A> option is on, Vim remembers the [c] flag and
	toggles <A HREF="motion.html#it">it</A> each time you use <A HREF="motion.html#it">it</A>, but resets <A HREF="motion.html#it">it</A> when you give a new
	search <A HREF="pattern.html#pattern">pattern</A>.
	{not in <A HREF="intro.html#Vi">Vi</A>: highlighting of the match, other responses than '<A HREF="#y">y</A>' or 'n'}

[e]     When the search <A HREF="pattern.html#pattern">pattern</A> fails, <A HREF="diff.html#do">do</A> not issue an error message and, in
	particular, continue in maps <A HREF="motion.html#as">as</A> if no error occurred.  This is most
	useful to prevent the &quot;No match&quot; error from breaking a <A HREF="map.html#mapping">mapping</A>.  Vim
	does not suppress the following error <A HREF="message.html#messages">messages</A>, however:
		Regular expressions can't be delimited by letters
		\ should be followed by /, ? or <A HREF="#&amp;">&amp;</A>
		No previous substitute regular <A HREF="eval.html#expression">expression</A>
		Trailing characters
		Interrupted
	{not in Vi}

[g]	<A HREF="insert.html#Replace">Replace</A> all occurrences in the line.  Without this argument,
	replacement occurs only for the first occurrence in each line.  If
	the <A HREF="options.html#'edcompatible'">'edcompatible'</A> option is on, Vim remembers this flag and toggles
	<A HREF="motion.html#it">it</A> each time you use <A HREF="motion.html#it">it</A>, but resets <A HREF="motion.html#it">it</A> when you give a new search
	<A HREF="pattern.html#pattern">pattern</A>.  If the <A HREF="options.html#'gdefault'">'gdefault'</A> option is on, this flag is on by default
	and the [g] argument switches <A HREF="motion.html#it">it</A> off.

[i]	Ignore <A HREF="#case">case</A> for the <A HREF="pattern.html#pattern">pattern</A>.  The <A HREF="options.html#'ignorecase'">'ignorecase'</A> and <A HREF="options.html#'smartcase'">'smartcase'</A> <A HREF="options.html#options">options</A>
	are not used.
	{not in Vi}

[I]	Don't ignore <A HREF="#case">case</A> for the <A HREF="pattern.html#pattern">pattern</A>.  The <A HREF="options.html#'ignorecase'">'ignorecase'</A> and <A HREF="options.html#'smartcase'">'smartcase'</A>
	<A HREF="options.html#options">options</A> are not used.
	{not in Vi}

[n]	Report the number of matches, <A HREF="diff.html#do">do</A> not actually substitute.  The [c]
	flag is ignored.  The matches are reported <A HREF="motion.html#as">as</A> if <A HREF="options.html#'report'">'report'</A> is zero.
	Useful to |<A HREF="tips.html#count-items">count-items</A>|.
	If \= |<A HREF="#sub-replace-expression">sub-replace-expression</A>| is used, the expression will be
	evaluated in the |<A HREF="eval.html#sandbox">sandbox</A>| at every match.

[p]	Print the line containing the last substitute.

[#]	Like [p] and prepend the line number.

[l]	Like [p] but print the text like |<A HREF="various.html#:list">:list</A>|.

[r]	Only useful in combination with `:&amp;` or `:s` without arguments.  `:&amp;r`
	works the same way <A HREF="motion.html#as">as</A> `:~`:  When the search <A HREF="pattern.html#pattern">pattern</A> is empty, use the
	previously used search <A HREF="pattern.html#pattern">pattern</A> instead of the search <A HREF="pattern.html#pattern">pattern</A> from the
	last substitute or `:global`.  If the last command that did a search
	was a substitute or `:global`, there is no effect.  If the last
	command was a search command such <A HREF="motion.html#as">as</A> &quot;<A HREF="pattern.html#/">/</A>&quot;, use the <A HREF="pattern.html#pattern">pattern</A> from that
	command.
	For `:s` with an argument this already happens:
<B>		:s/blue/red/</B>
<B>		/green</B>
<B>		:s//red/   or  :~   or  :&amp;r</B>
 	The last commands will replace &quot;green&quot; with &quot;red&quot;.
<B>		:s/blue/red/</B>
<B>		/green</B>
<B>		:&amp;</B>
 	The last command will replace &quot;blue&quot; with &quot;red&quot;.
	{not in Vi}

Note that there is no flag to change the &quot;magicness&quot; of the <A HREF="pattern.html#pattern">pattern</A>.  A
different command is used instead, or you can use |<A HREF="pattern.html#/\v">/\v</A>| and friends.  The
reason is that the flags can only be found by skipping the <A HREF="pattern.html#pattern">pattern</A>, and in
order to skip the <A HREF="pattern.html#pattern">pattern</A> the &quot;magicness&quot; must be known.  Catch 22!

If the {pattern} for the substitute command is empty, the command uses the
<A HREF="pattern.html#pattern">pattern</A> from the last substitute or `:global` command.  If there is none, but
there is a previous search <A HREF="pattern.html#pattern">pattern</A>, that one is used.  With the [r] flag, the
command uses the <A HREF="pattern.html#pattern">pattern</A> from the last substitute, `:global`, or search
command.

If the {string} is omitted the substitute is done <A HREF="motion.html#as">as</A> if it's empty.  Thus the
matched <A HREF="pattern.html#pattern">pattern</A> is deleted.  The separator after {pattern} can also be left
out then.  Example:
<B>	:%s/TESTING</B>
This deletes &quot;TESTING&quot; from all lines, but only one per line.

For compatibility with <A HREF="intro.html#Vi">Vi</A> these two exceptions are allowed:
&quot;\/{string}/&quot; and &quot;\?{string}?&quot; <A HREF="diff.html#do">do</A> the same <A HREF="motion.html#as">as</A> &quot;//{string}/r&quot;.
&quot;\&amp;{string}&amp;&quot; does the same <A HREF="motion.html#as">as</A> &quot;//{string}/&quot;.

							*<A NAME="E146"></A><B>E146</B>*
Instead of the '<A HREF="pattern.html#/">/</A>' which surrounds the <A HREF="pattern.html#pattern">pattern</A> and replacement <A HREF="eval.html#string">string</A>, you
can use any other single-byte character, but not an alphanumeric character,
'\', &#39;&#34;'' or '&#124;'.  This is useful if you want to include a '<A HREF="pattern.html#/">/</A>' in the search
<A HREF="pattern.html#pattern">pattern</A> or replacement <A HREF="eval.html#string">string</A>.  Example:
<B>	:s+/+//+</B>

For the definition of a pattern, see |<A HREF="pattern.html#pattern">pattern</A>|.  In <A HREF="visual.html#Visual">Visual</A> block mode, use
|<A HREF="pattern.html#/\&#37;V">/\&#37;V</A>| in the <A HREF="pattern.html#pattern">pattern</A> to have the substitute work in the block only.
Otherwise <A HREF="motion.html#it">it</A> works on whole lines anyway.


					*<A NAME="sub-replace-special"></A><B>sub-replace-special</B>* *<A NAME=":s\="></A><B>:s\=</B>*

|<A HREF="#sub-replace-expression">sub-replace-expression</A>|.  You can use that for complex replacement or special

Otherwise these characters in {string} have a special meaning:

The special meaning is also used inside the third argument {sub} of
the |<A HREF="eval.html#substitute()">substitute()</A>| function with the following exceptions:
  - A <A HREF="motion.html#&#37;">&#37;</A> inserts a percent literally without regard to <A HREF="options.html#'cpoptions'">'cpoptions'</A>.
  - magic is always set without regard to <A HREF="options.html#'magic'">'magic'</A>.
  - A ~ inserts a tilde literally.
  - <A HREF="motion.html#&lt;CR&gt;">&lt;CR&gt;</A> and \r inserts a <A HREF="intro.html#carriage-return">carriage-return</A> (CTRL-M).
  - \&lt;CR&gt; does not have a special meaning. it's just one of \x.

Examples:
<B>  :s/a\|b/xxx\0xxx/g		 modifies "a b"	     to "xxxaxxx xxxbxxx"</B>
<B>  :s/\([abc]\)\([efg]\)/\2\1/g	 modifies "af fa bg" to "fa fa gb"</B>
<B>  :s/abcde/abc^Mde/		 modifies "abcde"    to "abc", "de" (two lines)</B>
<B>  :s/$/\^M/			 modifies "abcde"    to "abcde^M"</B>
<B>  :s/\w\+/\u\0/g		 modifies "bla bla"  to "Bla Bla"</B>
<B>  :s/\w\+/\L\u\0/g		 modifies "BLA bla"  to "Bla Bla"</B>

Note: &quot;\L\u&quot; can be used to capitalize the first <A HREF="print.html#letter">letter</A> of a <A HREF="motion.html#word">word</A>.  This is
not compatible with <A HREF="intro.html#Vi">Vi</A> and older versions of Vim, where the &quot;\u&quot; would cancel
out the &quot;\L&quot;. Same for &quot;\U\l&quot;.

Note: In previous versions <A HREF="visual.html#CTRL-V">CTRL-V</A> was handled in a special way.  Since this is
not <A HREF="intro.html#Vi">Vi</A> compatible, this was removed.  Use a <A HREF="intro.html#backslash">backslash</A> instead.

<B><FONT COLOR="PURPLE">command		text	result </FONT></B>
:s/aa/a^Ma/	aa	a&lt;line-break&gt;a
:s/aa/a\^Ma/	aa	a^Ma
:s/aa/a\\^Ma/	aa	a\&lt;line-break&gt;a

(you need to type <A HREF="visual.html#CTRL-V">CTRL-V</A> <A HREF="motion.html#&lt;CR&gt;">&lt;CR&gt;</A> to get a ^M here)

The numbering of &quot;\1&quot;, &quot;\2&quot; etc. is done based on which &quot;\(&quot; comes first in
the <A HREF="pattern.html#pattern">pattern</A> (going left to right).  When a parentheses group matches several
times, the last one will be used for &quot;\1&quot;, &quot;\2&quot;, etc.  Example:
<B>  :s/\(\(a[a-d] \)*\)/\2/      modifies "aa ab x" to "ab x"</B>
The &quot;\2&quot; is for &quot;\(a[a-d] \)&quot;.  At first <A HREF="motion.html#it">it</A> matches &quot;aa &quot;<A HREF="motion.html#,">,</A> secondly &quot;<A HREF="motion.html#ab">ab</A> &quot;.

When using parentheses in combination with '&#124;', like in \([ab]\)\|\([cd]\),
either the first or second <A HREF="pattern.html#pattern">pattern</A> in parentheses did not match, so either
\1 or \2 is empty.  Example:
<B>  :s/\([ab]\)\|\([cd]\)/\1x/g   modifies "a b c d"  to "ax bx x x"</B>

When the substitute <A HREF="eval.html#string">string</A> starts with &quot;\=&quot; the remainder is interpreted <A HREF="motion.html#as">as</A> an
<A HREF="eval.html#expression">expression</A>.

The special meaning for characters <A HREF="motion.html#as">as</A> mentioned at |<A HREF="#sub-replace-special">sub-replace-special</A>| does
not apply except for &quot;<A HREF="motion.html#&lt;CR&gt;">&lt;CR&gt;</A>&quot;.  A <A HREF="motion.html#&lt;NL&gt;">&lt;NL&gt;</A> character is used <A HREF="motion.html#as">as</A> a line break, you
can get one with a double-quote <A HREF="eval.html#string">string</A>: &quot;\n&quot;.  Prepend a <A HREF="intro.html#backslash">backslash</A> to get a
real <A HREF="motion.html#&lt;NL&gt;">&lt;NL&gt;</A> character (which will be a NUL in the file).

The &quot;\=&quot; <A HREF="intro.html#notation">notation</A> can also be used inside the third argument {sub} of
|<A HREF="eval.html#substitute()">substitute()</A>| function.  In this <A HREF="#case">case</A>, the special meaning for characters <A HREF="motion.html#as">as</A>
mentioned at |<A HREF="#sub-replace-special">sub-replace-special</A>| does not apply at all. Especially, <A HREF="motion.html#&lt;CR&gt;">&lt;CR&gt;</A> and
<A HREF="motion.html#&lt;NL&gt;">&lt;NL&gt;</A> are interpreted not <A HREF="motion.html#as">as</A> a line break but <A HREF="motion.html#as">as</A> a <A HREF="intro.html#carriage-return">carriage-return</A> and a
new-line respectively.

When the result is a |<A HREF="eval.html#List">List</A>| then the items are joined with separating line
breaks.  Thus each item becomes a line, except that they can contain line
breaks themselves.

The whole matched text can be accessed with &quot;submatch(0)&quot;.  The text matched
with the first pair of () with &quot;submatch(1)&quot;.  Likewise for further
sub-matches in ().

Be careful: The separation character must not appear in the <A HREF="eval.html#expression">expression</A>!
Consider using a character like &quot;<A HREF="repeat.html#@">@</A>&quot; or &quot;<A HREF="cmdline.html#:">:</A>&quot;.  There is no problem if the result
of the <A HREF="eval.html#expression">expression</A> contains the separation character.

Examples:
<B>	:s@\n@\="\r" . expand("$HOME") . "\r"@</B>
This replaces an end-of-line with a new line containing the value of <A HREF="options.html#$HOME">$HOME</A>.

<B>	s/E/\="\&lt;Char-0x20ac&gt;"/g</B>
This replaces each '<A HREF="motion.html#E">E</A>' character with a euro sign.  Read more in |<A HREF="map.html#&lt;Char-&gt;">&lt;Char-&gt;</A>|.

			tabstop value given.  If you <A HREF="diff.html#do">do</A> not specify a new
			tabstop size or <A HREF="motion.html#it">it</A> is zero, Vim uses the current value
			of <A HREF="options.html#'tabstop'">'tabstop'</A>.
			The current value of <A HREF="options.html#'tabstop'">'tabstop'</A> is always used to
			compute the width of existing tabs.
			With !, Vim also replaces strings of only normal
			spaces with tabs where appropriate.
			With <A HREF="options.html#'expandtab'">'expandtab'</A> on, Vim replaces all tabs with the
			appropriate number of spaces.
			This command sets <A HREF="options.html#'tabstop'">'tabstop'</A> to the new value given,
			and if performed on the whole file, which is default,
			should not make any visible change.
			Careful: This command modifies any <A HREF="motion.html#&lt;Tab&gt;">&lt;Tab&gt;</A> characters
			inside of strings in a C program.  Use &quot;\t&quot; to avoid
			this (that's a good habit anyway).
			`:retab!` may also change a sequence of spaces by
			<A HREF="motion.html#&lt;Tab&gt;">&lt;Tab&gt;</A> characters, which can mess up a <A HREF="eval.html#printf()">printf()</A>.

[&quot;x]y{motion}		Yank <A HREF="intro.html#{motion}">{motion}</A> text [into <A HREF="sponsor.html#register">register</A> x].  When no
			characters are to be yanked (e.g., &quot;y0&quot; in column 1),

[&quot;x]&lt;MiddleMouse&gt;	Put the text from a <A HREF="sponsor.html#register">register</A> before the cursor <A HREF="intro.html#[count]">[count]</A>
			times.  Uses the &quot;* <A HREF="sponsor.html#register">register</A>, unless another is
			specified.
			Leaves the cursor at the end of the new text.
			Using the mouse only works when <A HREF="options.html#'mouse'">'mouse'</A> contains '<A HREF="pattern.html#n">n</A>'
			or '<A HREF="insert.html#a">a</A>'.
			{not in Vi}
			If you have a scrollwheel and often accidentally paste
			text, you can use these mappings to disable the
			pasting with the middle mouse button:
<B>				:map &lt;MiddleMouse&gt; &lt;Nop&gt;</B>
<B>				:imap &lt;MiddleMouse&gt; &lt;Nop&gt;</B>
 			You might want to disable the multi-click versions

							*<A NAME="gp"></A><B>gp</B>*
[&quot;x]gp			Just like &quot;<A HREF="#p">p</A>&quot;, but leave the cursor just after the new

							*<A NAME="gP"></A><B>gP</B>*
[&quot;x]gP			Just like &quot;<A HREF="#P">P</A>&quot;, but leave the cursor just after the new
			text.  {not in Vi}


							*<A NAME=":pu"></A><B>:pu</B>* *<A NAME=":put"></A><B>:put</B>*
:[line]pu[t] [x]	Put the text [from <A HREF="sponsor.html#register">register</A> x] after [line] (default
			current line).  This always works |<A HREF="motion.html#linewise">linewise</A>|, thus
			this command can be used to put a yanked block <A HREF="motion.html#as">as</A> new
			lines.
			If no <A HREF="sponsor.html#register">register</A> is specified, <A HREF="motion.html#it">it</A> depends on the <A HREF="options.html#'cb'">'cb'</A>
			option: If <A HREF="options.html#'cb'">'cb'</A> contains &quot;unnamedplus&quot;, paste from the
			+ <A HREF="sponsor.html#register">register</A> |<A HREF="gui_x11.html#quoteplus">quoteplus</A>|.  Otherwise, if <A HREF="options.html#'cb'">'cb'</A> contains
			&quot;unnamed&quot;, paste from the &#42; <A HREF="sponsor.html#register">register</A> |<A HREF="gui.html#quotestar">quotestar</A>|.
			Otherwise, paste from the unnamed <A HREF="sponsor.html#register">register</A>
			|<A HREF="#quote_quote">quote_quote</A>|.
			The <A HREF="sponsor.html#register">register</A> can also be '<A HREF="#=">=</A>' followed by an optional
			<A HREF="eval.html#expression">expression</A>.  The <A HREF="eval.html#expression">expression</A> continues until the end of
			the command.  You need to <A HREF="intro.html#escape">escape</A> the '&#124;' and &#39;&#34;''
			characters to prevent them from terminating the
			command.  Example:
<B>				:put ='path' . \",/test\"</B>
 			If there is no <A HREF="eval.html#expression">expression</A> after '<A HREF="#=">=</A>', Vim uses the
			previous <A HREF="eval.html#expression">expression</A>.  You can see <A HREF="motion.html#it">it</A> with &quot;:dis =&quot;.

:[line]pu[t]! [x]	Put the text [from <A HREF="sponsor.html#register">register</A> x] before [line] (default
			current line).


[&quot;x]]p		    or					*<A NAME="]p"></A><B>]p</B>* *<A NAME="]&lt;MiddleMouse&gt;"></A><B>]&lt;MiddleMouse&gt;</B>*
[&quot;x]]&lt;MiddleMouse&gt;	Like &quot;<A HREF="#p">p</A>&quot;, but adjust the indent to the current line.
			Using the mouse only works when <A HREF="options.html#'mouse'">'mouse'</A> contains '<A HREF="pattern.html#n">n</A>'
			or '<A HREF="insert.html#a">a</A>'.  {not in Vi}


[&quot;x][P		    or					*<A NAME="[P"></A><B>[P</B>*

[&quot;x]]P		    or					*<A NAME="]P"></A><B>]P</B>*

[&quot;x][p		    or					*<A NAME="[p"></A><B>[p</B>* *<A NAME="[&lt;MiddleMouse&gt;"></A><B>[&lt;MiddleMouse&gt;</B>*
[&quot;x][&lt;MiddleMouse&gt;	Like &quot;<A HREF="#P">P</A>&quot;, but adjust the indent to the current line.
			Using the mouse only works when <A HREF="options.html#'mouse'">'mouse'</A> contains '<A HREF="pattern.html#n">n</A>'
			or '<A HREF="insert.html#a">a</A>'.  {not in Vi}

You can use these commands to copy text from one place to another.  Do this
by first getting the text into a <A HREF="sponsor.html#register">register</A> with a <A HREF="#yank">yank</A>, delete or change
command, then <A HREF="insert.html#inserting">inserting</A> the <A HREF="sponsor.html#register">register</A> contents with a put command.  You can
also use these commands to move text from one file to another, because Vim
preserves all <A HREF="#registers">registers</A> when <A HREF="#changing">changing</A> <A HREF="windows.html#buffers">buffers</A> (the <A HREF="editing.html#CTRL-^">CTRL-^</A> command is a quick
way to toggle between two files).


				*<A NAME="linewise-register"></A><B>linewise-register</B>* *<A NAME="characterwise-register"></A><B>characterwise-register</B>*
You can repeat the put commands with &quot;<A HREF="repeat.html#.">.</A>&quot; (except for <A HREF="#:put">:put</A>) and <A HREF="undo.html#undo">undo</A> them.  If
the command that was used to get the text into the <A HREF="sponsor.html#register">register</A> was |<A HREF="motion.html#linewise">linewise</A>|,
Vim inserts the text below (&quot;p&quot;) or above (&quot;P&quot;) the line where the cursor is.
Otherwise Vim inserts the text after (&quot;p&quot;) or before (&quot;P&quot;) the cursor.  With
the &quot;<A HREF="#:put">:put</A>&quot; command, Vim always inserts the text in the next line.  You can
exchange two characters with the command sequence &quot;xp&quot;.  You can exchange two
lines with the command sequence &quot;ddp&quot;.  You can exchange two words with the
command sequence &quot;deep&quot; (start with the cursor in the blank space before the
first <A HREF="motion.html#word">word</A>).  You can use the &quot;<A HREF="motion.html#']">']</A>&quot; or &quot;<A HREF="motion.html#`]">`]</A>&quot; command after the put command to
move the cursor to the end of the inserted text, or use &quot;<A HREF="motion.html#'[">'[</A>&quot; or &quot;<A HREF="motion.html#`[">`[</A>&quot; to move
the cursor to the start.


						*<A NAME="put-Visual-mode"></A><B>put-Visual-mode</B>* *<A NAME="v_p"></A><B>v_p</B>* *<A NAME="v_P"></A><B>v_P</B>*
When using a put command like |<A HREF="#p">p</A>| or |<A HREF="#P">P</A>| in <A HREF="visual.html#Visual">Visual</A> mode, Vim will try to
replace the selected text with the contents of the <A HREF="sponsor.html#register">register</A>.  Whether this
works well depends on the type of selection and the type of the text in the
<A HREF="sponsor.html#register">register</A>.  With blockwise selection <A HREF="motion.html#it">it</A> also depends on the size of the block
and whether the corners are on an existing character.  (Implementation detail:
<A HREF="motion.html#it">it</A> actually works by first putting the <A HREF="sponsor.html#register">register</A> after the selection and then
<A HREF="#deleting">deleting</A> the selection.)
The previously selected text is put in the unnamed <A HREF="sponsor.html#register">register</A>.  If you want to
put the same text into a <A HREF="visual.html#Visual">Visual</A> selection several times you need to use
another <A HREF="sponsor.html#register">register</A>.  E.g., <A HREF="#yank">yank</A> the text to copy, Visually select the text to
replace and use &quot;0p .  You can repeat this <A HREF="motion.html#as">as</A> many times <A HREF="motion.html#as">as</A> you like, the
unnamed <A HREF="sponsor.html#register">register</A> will be changed each time.

When you use a blockwise <A HREF="visual.html#Visual">Visual</A> mode command and <A HREF="#yank">yank</A> only a single line into
a <A HREF="sponsor.html#register">register</A>, a paste on a visual selected area will paste that single line on
each of the selected lines (thus <A HREF="#replacing">replacing</A> the blockwise selected region by a
block of the pasted line).


							*<A NAME="blockwise-register"></A><B>blockwise-register</B>*
If you use a blockwise <A HREF="visual.html#Visual">Visual</A> mode command to get the text into the <A HREF="sponsor.html#register">register</A>,
the block of text will be inserted before (&quot;P&quot;) or after (&quot;p&quot;) the cursor
column in the current and next lines.  Vim makes the whole block of text start
in the same column.  Thus the inserted text looks the same <A HREF="motion.html#as">as</A> when <A HREF="motion.html#it">it</A> was
yanked or deleted.  Vim may replace some <A HREF="motion.html#&lt;Tab&gt;">&lt;Tab&gt;</A> characters with spaces to make
this happen.  However, if the width of the block is not a multiple of a <A HREF="motion.html#&lt;Tab&gt;">&lt;Tab&gt;</A>
width and the text after the inserted block contains &lt;Tab&gt;s, that text may be
misaligned.

Note that after a <A HREF="motion.html#characterwise">characterwise</A> <A HREF="#yank">yank</A> command, Vim leaves the cursor on the
first yanked character that is closest to the start of the buffer.  This means
that &quot;yl&quot; doesn't move the cursor, but &quot;yh&quot; moves the cursor one character
left.
Rationale:	In <A HREF="intro.html#Vi">Vi</A> the &quot;<A HREF="#y">y</A>&quot; command followed by a backwards motion would
		sometimes not move the cursor to the first yanked character,
		because redisplaying was skipped.  In Vim <A HREF="motion.html#it">it</A> always moves to
		the first character, <A HREF="motion.html#as">as</A> specified by <A HREF="intro.html#Posix">Posix</A>.
With a <A HREF="motion.html#linewise">linewise</A> <A HREF="#yank">yank</A> command the cursor is put in the first line, but the
column is unmodified, thus <A HREF="motion.html#it">it</A> may not be on the first yanked character.


There are ten types of <A HREF="#registers">registers</A>:			*<A NAME="registers"></A><B>registers</B>* *<A NAME="E354"></A><B>E354</B>*
1. The unnamed <A HREF="sponsor.html#register">register</A> &quot;&quot;
2. 10 numbered <A HREF="#registers">registers</A> &quot;<A HREF="motion.html#0">0</A> to &quot;9
3. The small delete <A HREF="sponsor.html#register">register</A> &quot;<A HREF="motion.html#-">-</A>
4. 26 named <A HREF="#registers">registers</A> &quot;a to &quot;<A HREF="index.html#z">z</A> or &quot;A to &quot;Z
5. three read-only <A HREF="#registers">registers</A> &quot;<A HREF="cmdline.html#:,">:,</A> &quot;., &quot;<A HREF="motion.html#&#37;">&#37;</A>
6. alternate buffer <A HREF="sponsor.html#register">register</A> &quot;<A HREF="pattern.html##">#</A>
7. the <A HREF="eval.html#expression">expression</A> <A HREF="sponsor.html#register">register</A> &quot;<A HREF="#=">=</A>
8. The selection and drop <A HREF="#registers">registers</A> &quot;*, &quot;<A HREF="motion.html#+">+</A> and &quot;<A HREF="#~">~</A> 
9. The black hole <A HREF="sponsor.html#register">register</A> &quot;<A HREF="motion.html#_">_</A>
10. Last search <A HREF="pattern.html#pattern">pattern</A> <A HREF="sponsor.html#register">register</A> &quot;<A HREF="pattern.html#/">/</A>


1. Unnamed <A HREF="sponsor.html#register">register</A> &quot;&quot;				*<A NAME="quote_quote"></A><B>quote_quote</B>* *<A NAME="quotequote"></A><B>quotequote</B>*
Vim fills this <A HREF="sponsor.html#register">register</A> with text deleted with the &quot;<A HREF="#d">d</A>&quot;, &quot;<A HREF="#c">c</A>&quot;, &quot;<A HREF="#s">s</A>&quot;, &quot;<A HREF="#x">x</A>&quot; commands
or copied with the <A HREF="#yank">yank</A> &quot;<A HREF="#y">y</A>&quot; command, regardless of whether or not a specific
<A HREF="sponsor.html#register">register</A> was used (e.g.  &quot;xdd).  This is like the unnamed <A HREF="sponsor.html#register">register</A> is pointing
to the last used <A HREF="sponsor.html#register">register</A>.  Thus when appending using an <A HREF="#uppercase">uppercase</A> <A HREF="sponsor.html#register">register</A>
name, the unnamed <A HREF="sponsor.html#register">register</A> contains the same text <A HREF="motion.html#as">as</A> the named <A HREF="sponsor.html#register">register</A>.
An exception is the '<A HREF="motion.html#_">_</A>' <A HREF="sponsor.html#register">register</A>: &quot;_dd does not store the deleted text in any
<A HREF="sponsor.html#register">register</A>.
Vim uses the contents of the unnamed <A HREF="sponsor.html#register">register</A> for any put command (p or <A HREF="#P">P</A>)
which does not specify a <A HREF="sponsor.html#register">register</A>.  Additionally you can access <A HREF="motion.html#it">it</A> with the
name &#39;&#34;''.  This means you have to type two double <A HREF="quotes.html#quotes">quotes</A>.  Writing to the &quot;&quot;
<A HREF="sponsor.html#register">register</A> writes to <A HREF="sponsor.html#register">register</A> &quot;0.
{Vi: <A HREF="sponsor.html#register">register</A> contents are lost when <A HREF="#changing">changing</A> files, no &#39;&#34;''}


2. Numbered <A HREF="#registers">registers</A> &quot;<A HREF="motion.html#0">0</A> to &quot;9		*<A NAME="quote_number"></A><B>quote_number</B>* *<A NAME="quote0"></A><B>quote0</B>* *<A NAME="quote1"></A><B>quote1</B>*

					*<A NAME="quote2"></A><B>quote2</B>* *<A NAME="quote3"></A><B>quote3</B>* *<A NAME="quote4"></A><B>quote4</B>* *<A NAME="quote9"></A><B>quote9</B>*
Vim fills these <A HREF="#registers">registers</A> with text from <A HREF="#yank">yank</A> and delete commands.
   Numbered <A HREF="sponsor.html#register">register</A> 0 contains the text from the most recent <A HREF="#yank">yank</A> command,
unless the command specified another <A HREF="sponsor.html#register">register</A> with [&quot;x].
   Numbered <A HREF="sponsor.html#register">register</A> 1 contains the text deleted by the most recent delete or
change command, unless the command specified another <A HREF="sponsor.html#register">register</A> or the text is
<A HREF="various.html#less">less</A> than one line (the small delete <A HREF="sponsor.html#register">register</A> is used then).  An exception is
made for the delete <A HREF="motion.html#operator">operator</A> with these <A HREF="intro.html#movement">movement</A> commands: |<A HREF="motion.html#&#37;">&#37;</A>|, |<A HREF="motion.html#(">(</A>|, |<A HREF="motion.html#)">)</A>|, |<A HREF="motion.html#`">`</A>|,
|<A HREF="pattern.html#/">/</A>|, |<A HREF="pattern.html#?">?</A>|, |<A HREF="pattern.html#n">n</A>|, |<A HREF="pattern.html#N">N</A>|, |<A HREF="motion.html#{">{</A>| and |<A HREF="motion.html#}">}</A>|.  Register &quot;1 is always used then (this is <A HREF="intro.html#Vi">Vi</A>
compatible).  The &quot;<A HREF="motion.html#-">-</A> <A HREF="sponsor.html#register">register</A> is used <A HREF="motion.html#as">as</A> well if the delete is within a line.
Note that these characters may be mapped.  E.g. |<A HREF="motion.html#&#37;">&#37;</A>| is mapped by the matchit
<A HREF="usr_05.html#plugin">plugin</A>.
   With each successive deletion or change, Vim shifts the previous contents
of <A HREF="sponsor.html#register">register</A> 1 into <A HREF="sponsor.html#register">register</A> 2, 2 into 3, and so forth, losing the previous
contents of <A HREF="sponsor.html#register">register</A> 9.
{Vi: numbered <A HREF="sponsor.html#register">register</A> contents are lost when <A HREF="#changing">changing</A> files; <A HREF="sponsor.html#register">register</A> 0 does
not exist}


3. Small delete <A HREF="sponsor.html#register">register</A> &quot;<A HREF="motion.html#-">-</A>				*<A NAME="quote_-"></A><B>quote_-</B>* *<A NAME="quote-"></A><B>quote-</B>*
This <A HREF="sponsor.html#register">register</A> contains text from commands that delete <A HREF="various.html#less">less</A> than one line,
except when the command specifies a <A HREF="sponsor.html#register">register</A> with [&quot;x].
{not in Vi}


4. Named <A HREF="#registers">registers</A> &quot;a to &quot;<A HREF="index.html#z">z</A> or &quot;A to &quot;Z			*<A NAME="quote_alpha"></A><B>quote_alpha</B>* *<A NAME="quotea"></A><B>quotea</B>*
Vim fills these <A HREF="#registers">registers</A> only when you say so.  Specify them <A HREF="motion.html#as">as</A> <A HREF="#lowercase">lowercase</A>
letters to replace their previous contents or <A HREF="motion.html#as">as</A> <A HREF="#uppercase">uppercase</A> letters to append
to their previous contents.  When the '<A HREF="#&gt;">&gt;</A>' flag is present in <A HREF="options.html#'cpoptions'">'cpoptions'</A> then
a line break is inserted before the appended text.

5. Read-only <A HREF="#registers">registers</A> &quot;<A HREF="cmdline.html#:,">:,</A> &quot;. and &quot;<A HREF="motion.html#&#37;">&#37;</A>
These are '<A HREF="motion.html#&#37;">&#37;</A>', '<A HREF="pattern.html##">#</A>', '<A HREF="cmdline.html#:">:</A>' and '<A HREF="repeat.html#.">.</A>'.  You can use them only with the &quot;<A HREF="#p">p</A>&quot;, &quot;<A HREF="#P">P</A>&quot;,
and &quot;<A HREF="#:put">:put</A>&quot; commands and with <A HREF="undo.html#CTRL-R">CTRL-R</A>.  {not in Vi}

						*<A NAME="quote_."></A><B>quote_.</B>* *<A NAME="quote."></A><B>quote.</B>* *<A NAME="E29"></A><B>E29</B>*
	&quot;.	Contains the last inserted text (the same <A HREF="motion.html#as">as</A> what is inserted
		with the insert mode commands <A HREF="#CTRL-A">CTRL-A</A> and CTRL-@).  Note: this
		doesn't work with <A HREF="undo.html#CTRL-R">CTRL-R</A> on the command-line.  It works a bit
		differently, like <A HREF="insert.html#inserting">inserting</A> the text instead of putting <A HREF="motion.html#it">it</A>
		('textwidth' and other <A HREF="options.html#options">options</A> affect what is inserted).

							*<A NAME="quote_&#37;"></A><B>quote_&#37;</B>* *<A NAME="quote&#37;"></A><B>quote&#37;</B>*
	&quot;<A HREF="motion.html#&#37;">&#37;</A>	Contains the name of the current file.

						*<A NAME="quote_:"></A><B>quote_:</B>* *<A NAME="quote:"></A><B>quote:</B>* *<A NAME="E30"></A><B>E30</B>*
	&quot;:	Contains the most recent executed command-line.  Example: Use

6. Alternate file <A HREF="sponsor.html#register">register</A> &quot;<A HREF="pattern.html##">#</A>
Contains the name of the alternate file for the current <A HREF="windows.html#window">window</A>.  It will
change how the |<A HREF="editing.html#CTRL-^">CTRL-^</A>| command works.
This <A HREF="sponsor.html#register">register</A> is writable, mainly to allow for restoring <A HREF="motion.html#it">it</A> after a <A HREF="usr_05.html#plugin">plugin</A> has
changed <A HREF="motion.html#it">it</A>.  It accepts buffer number:
<B>    let altbuf = bufnr(@#)</B>
<B>    ...</B>
<B>    let @# = altbuf</B>
It will give error |<A HREF="windows.html#E86">E86</A>| if you pass buffer number and this buffer does not
exist.
It can also accept a match with an existing buffer name:
<B>    let @# = 'buffer_name'</B>
Error |<A HREF="windows.html#E93">E93</A>| if there is more than one buffer matching the given name or |<A HREF="windows.html#E94">E94</A>|
if none of <A HREF="windows.html#buffers">buffers</A> matches the given name.


7. Expression <A HREF="sponsor.html#register">register</A> &quot;<A HREF="#=">=</A>			*<A NAME="quote_="></A><B>quote_=</B>* *<A NAME="quote="></A><B>quote=</B>* *<A NAME="@="></A><B>@=</B>*
This is not really a <A HREF="sponsor.html#register">register</A> that stores text, but is a way to use an
<A HREF="eval.html#expression">expression</A> in commands which use a <A HREF="sponsor.html#register">register</A>.  The <A HREF="eval.html#expression">expression</A> <A HREF="sponsor.html#register">register</A> is
read-write.

When typing the '<A HREF="#=">=</A>' after &quot; or <A HREF="undo.html#CTRL-R">CTRL-R</A> the cursor moves to the command-line,
where you can enter any expression (see |<A HREF="eval.html#expression">expression</A>|).  All normal
command-line editing commands are available, including a special <A HREF="cmdline.html#history">history</A> for
expressions.  When you end the command-line by typing <A HREF="motion.html#&lt;CR&gt;">&lt;CR&gt;</A>, Vim computes the
result of the <A HREF="eval.html#expression">expression</A>.  If you end <A HREF="motion.html#it">it</A> with <A HREF="intro.html#&lt;Esc&gt;">&lt;Esc&gt;</A>, Vim abandons the
<A HREF="eval.html#expression">expression</A>.  If you <A HREF="diff.html#do">do</A> not enter an <A HREF="eval.html#expression">expression</A>, Vim uses the previous
<A HREF="eval.html#expression">expression</A> (like with the &quot;<A HREF="pattern.html#/">/</A>&quot; command).

The <A HREF="eval.html#expression">expression</A> must evaluate to a <A HREF="eval.html#String">String</A>.  A <A HREF="eval.html#Number">Number</A> is always automatically
converted to a <A HREF="eval.html#String">String</A>.  For the &quot;<A HREF="#p">p</A>&quot; and &quot;<A HREF="#:put">:put</A>&quot; command, if the result is a
<A HREF="eval.html#Float">Float</A> it's converted into a <A HREF="eval.html#String">String</A>.  If the result is a <A HREF="eval.html#List">List</A> each element is
turned into a <A HREF="eval.html#String">String</A> and used <A HREF="motion.html#as">as</A> a line.  A <A HREF="eval.html#Dictionary">Dictionary</A> or FuncRef results in
an error message (use <A HREF="eval.html#string()">string()</A> to convert).

If the &quot;<A HREF="#=">=</A> <A HREF="sponsor.html#register">register</A> is used for the &quot;<A HREF="#p">p</A>&quot; command, the <A HREF="eval.html#String">String</A> is split up at <A HREF="motion.html#&lt;NL&gt;">&lt;NL&gt;</A>
characters.  If the <A HREF="eval.html#String">String</A> ends in a <A HREF="motion.html#&lt;NL&gt;">&lt;NL&gt;</A>, <A HREF="motion.html#it">it</A> is regarded <A HREF="motion.html#as">as</A> a <A HREF="motion.html#linewise">linewise</A>
<A HREF="sponsor.html#register">register</A>.  {not in Vi}

8. Selection and drop <A HREF="#registers">registers</A> &quot;*, &quot;<A HREF="motion.html#+">+</A> and &quot;<A HREF="#~">~</A> 
Use these <A HREF="#registers">registers</A> for storing and retrieving the selected text for the <A HREF="gui.html#GUI">GUI</A>.
See |<A HREF="gui.html#quotestar">quotestar</A>| and |<A HREF="gui_x11.html#quoteplus">quoteplus</A>|.  When the <A HREF="gui.html#clipboard">clipboard</A> is not available or not
working, the unnamed <A HREF="sponsor.html#register">register</A> is used instead.  For <A HREF="os_unix.html#Unix">Unix</A> systems the <A HREF="gui.html#clipboard">clipboard</A>
is only available when the |<A HREF="various.html#+xterm_clipboard">+xterm_clipboard</A>| feature is present.  {not in Vi}

Note that there is only a distinction between &quot;* and &quot;<A HREF="motion.html#+">+</A> for <A HREF="options.html#X11">X11</A> systems.  For
an explanation of the difference, see |<A HREF="gui_x11.html#x11-selection">x11-selection</A>|.  Under <A HREF="os_win32.html#MS-Windows">MS-Windows</A>, use
of &quot;* and &quot;<A HREF="motion.html#+">+</A> is actually synonymous and refers to the |<A HREF="gui_w32.html#gui-clipboard">gui-clipboard</A>|.


						*<A NAME="quote_~"></A><B>quote_~</B>* *<A NAME="quote~"></A><B>quote~</B>* *<A NAME="&lt;Drop&gt;"></A><B>&lt;Drop&gt;</B>*
The read-only &quot;<A HREF="#~">~</A> <A HREF="sponsor.html#register">register</A> stores the dropped text from the last drag'n'drop
operation.  When something has been dropped onto Vim, the &quot;<A HREF="#~">~</A> <A HREF="sponsor.html#register">register</A> is
filled in and the <A HREF="#&lt;Drop&gt;">&lt;Drop&gt;</A> pseudo key is sent for notification.  You can remap
this key if you want; the default action (for all modes) is to insert the
contents of the &quot;<A HREF="#~">~</A> <A HREF="sponsor.html#register">register</A> at the cursor position.  {not in Vi}
{only available when compiled with the |<A HREF="various.html#+dnd">+dnd</A>| feature, currently only with the
<A HREF="gui_x11.html#GTK">GTK</A> GUI}

Note: The &quot;<A HREF="#~">~</A> <A HREF="sponsor.html#register">register</A> is only used when dropping plain text onto Vim.
Drag'n'drop of URI lists is handled internally.


9. Black hole <A HREF="sponsor.html#register">register</A> &quot;<A HREF="motion.html#_">_</A>				*<A NAME="quote_"></A><B>quote_</B>*
When <A HREF="editing.html#writing">writing</A> to this <A HREF="sponsor.html#register">register</A>, nothing happens.  This can be used to delete
text without affecting the normal <A HREF="#registers">registers</A>.  When reading from this <A HREF="sponsor.html#register">register</A>,
nothing is returned.  {not in Vi}

10. Last search <A HREF="pattern.html#pattern">pattern</A> <A HREF="sponsor.html#register">register</A>	&quot;<A HREF="pattern.html#/">/</A>			*quote_/* *quote/*
Contains the most recent <A HREF="pattern.html#search-pattern">search-pattern</A>.  This is used for &quot;<A HREF="pattern.html#n">n</A>&quot; and <A HREF="options.html#'hlsearch'">'hlsearch'</A>.
It is writable with `:let`, you can change <A HREF="motion.html#it">it</A> to have <A HREF="options.html#'hlsearch'">'hlsearch'</A> highlight
other matches without actually searching.  You can't <A HREF="#yank">yank</A> or delete into this
<A HREF="sponsor.html#register">register</A>.  The search direction is available in |<A HREF="eval.html#v:searchforward">v:searchforward</A>|.
Note that the value is restored when returning from a function
|<A HREF="eval.html#function-search-undo">function-search-undo</A>|.
{not in Vi}


							*<A NAME="@/"></A><B>@/</B>*
You can write to a <A HREF="sponsor.html#register">register</A> with a `:let` command |<A HREF="eval.html#:let-@">:let-@</A>|.  Example:
<B>	:let @/ = "the"</B>

If you use a put command without specifying a <A HREF="sponsor.html#register">register</A>, Vim uses the <A HREF="sponsor.html#register">register</A>
that was last filled (this is also the contents of the unnamed <A HREF="sponsor.html#register">register</A>).  If
you are confused, use the `:dis` command to find out what Vim will put (this
command displays all named and numbered <A HREF="#registers">registers</A>; the unnamed <A HREF="sponsor.html#register">register</A> is
labelled &#39;&#34;'').

The next three commands always work on whole lines.


:[range]co[py] <A HREF="cmdline.html#{address}">{address}</A>				*<A NAME=":co"></A><B>:co</B>* *<A NAME=":copy"></A><B>:copy</B>*
			Copy the lines given by <A HREF="cmdline.html#[range]">[range]</A> to below the line
			given by <A HREF="cmdline.html#{address}">{address}</A>.


							*<A NAME=":t"></A><B>:t</B>*
<A HREF="#:t">:t</A>			Synonym for copy.


:[range]m[ove] <A HREF="cmdline.html#{address}">{address}</A>			*<A NAME=":m"></A><B>:m</B>* *<A NAME=":mo"></A><B>:mo</B>* *<A NAME=":move"></A><B>:move</B>* *<A NAME="E134"></A><B>E134</B>*
			Move the lines given by <A HREF="cmdline.html#[range]">[range]</A> to below the line
			given by <A HREF="cmdline.html#{address}">{address}</A>.

==============================================================================

6. Formatting text					*<A NAME="formatting"></A><B>formatting</B>*


:[range]ce[nter] [width]				*<A NAME=":ce"></A><B>:ce</B>* *<A NAME=":center"></A><B>:center</B>*
			Center lines in <A HREF="cmdline.html#[range]">[range]</A> between [width] columns
			(default <A HREF="options.html#'textwidth'">'textwidth'</A> or 80 when <A HREF="options.html#'textwidth'">'textwidth'</A> is 0).
			{not in Vi}


:[range]ri[ght] [width]					*<A NAME=":ri"></A><B>:ri</B>* *<A NAME=":right"></A><B>:right</B>*
			Right-align lines in <A HREF="cmdline.html#[range]">[range]</A> at [width] columns
			(default <A HREF="options.html#'textwidth'">'textwidth'</A> or 80 when <A HREF="options.html#'textwidth'">'textwidth'</A> is 0).
			{not in Vi}


							*<A NAME=":le"></A><B>:le</B>* *<A NAME=":left"></A><B>:left</B>*
:[range]le[ft] [indent]
			Left-align lines in <A HREF="cmdline.html#[range]">[range]</A>.  Sets the indent in the
			lines to [indent] (default 0).  {not in Vi}


							*<A NAME="gq"></A><B>gq</B>*
gq{motion}		Format the lines that <A HREF="intro.html#{motion}">{motion}</A> moves over.
			Formatting is done with one of three methods:
			1. If <A HREF="options.html#'formatexpr'">'formatexpr'</A> is not empty the <A HREF="eval.html#expression">expression</A> is
			   evaluated.  This can differ for each buffer.
			2. If <A HREF="options.html#'formatprg'">'formatprg'</A> is not empty an external program
			   is used.
			3. Otherwise <A HREF="#formatting">formatting</A> is done internally.

			In the third <A HREF="#case">case</A> the <A HREF="options.html#'textwidth'">'textwidth'</A> option controls the
			length of each formatted line (see below).
			If the <A HREF="options.html#'textwidth'">'textwidth'</A> option is 0, the formatted line
			length is the screen width (with a maximum width of
			79).
			The <A HREF="options.html#'formatoptions'">'formatoptions'</A> option controls the type of
			<A HREF="#formatting">formatting</A> |<A HREF="#fo-table">fo-table</A>|.
			The cursor is left on the first non-blank of the last
			formatted line.
			NOTE: The &quot;<A HREF="intro.html#Q">Q</A>&quot; command formerly performed this
			function.  If you still want to use &quot;<A HREF="intro.html#Q">Q</A>&quot; for
			<A HREF="#formatting">formatting</A>, use this <A HREF="map.html#mapping">mapping</A>:
<B>				:nnoremap Q gq</B>


<A HREF="#gqgq">gqgq</A>							*<A NAME="gqgq"></A><B>gqgq</B>* *<A NAME="gqq"></A><B>gqq</B>*
<A HREF="#gqq">gqq</A>			Format the current line.  With a <A HREF="intro.html#count">count</A> format that
			many lines.  {not in Vi}


							*<A NAME="v_gq"></A><B>v_gq</B>*
{Visual}gq		Format the highlighted text.  (for <A HREF="intro.html#{Visual}">{Visual}</A> see
			|<A HREF="visual.html#Visual-mode">Visual-mode</A>|).  {not in Vi}


							*<A NAME="gw"></A><B>gw</B>*
gw{motion}		Format the lines that <A HREF="intro.html#{motion}">{motion}</A> moves over.  Similar to
			|<A HREF="#gq">gq</A>| but puts the cursor back at the same position in
			the text.  However, <A HREF="options.html#'formatprg'">'formatprg'</A> and <A HREF="options.html#'formatexpr'">'formatexpr'</A> are
			not used.  {not in Vi}


<A HREF="#gwgw">gwgw</A>							*<A NAME="gwgw"></A><B>gwgw</B>* *<A NAME="gww"></A><B>gww</B>*
<A HREF="#gww">gww</A>			Format the current line <A HREF="motion.html#as">as</A> with &quot;<A HREF="#gw">gw</A>&quot;.  {not in Vi}


							*<A NAME="v_gw"></A><B>v_gw</B>*
{Visual}gw		Format the highlighted text <A HREF="motion.html#as">as</A> with &quot;<A HREF="#gw">gw</A>&quot;.  (for
			<A HREF="intro.html#{Visual}">{Visual}</A> see |<A HREF="visual.html#Visual-mode">Visual-mode</A>|).  {not in Vi}


Example: To format the current <A HREF="motion.html#paragraph">paragraph</A> use:			*<A NAME="gqap"></A><B>gqap</B>* 
<B>	gqap</B>

The &quot;<A HREF="#gq">gq</A>&quot; command leaves the cursor in the line where the motion command takes
the cursor.  This allows you to repeat <A HREF="#formatting">formatting</A> repeated with &quot;<A HREF="repeat.html#.">.</A>&quot;.  This
works well with &quot;gqj&quot; (format current and next line) and &quot;gq}&quot; (format until
end of <A HREF="motion.html#paragraph">paragraph</A>).  Note: When <A HREF="options.html#'formatprg'">'formatprg'</A> is set, &quot;<A HREF="#gq">gq</A>&quot; leaves the cursor on
the first formatted line (as with using a <A HREF="#filter">filter</A> command).

If you want to format the current <A HREF="motion.html#paragraph">paragraph</A> and continue where you were, use:
<B>	gwap</B>
If you always want to keep paragraphs formatted you may want to add the '<A HREF="insert.html#a">a</A>'
flag to <A HREF="options.html#'formatoptions'">'formatoptions'</A>.  See |<A HREF="#auto-format">auto-format</A>|.

If the <A HREF="options.html#'autoindent'">'autoindent'</A> option is on, Vim uses the indent of the first line for
the following lines.

Formatting does not change empty lines (but <A HREF="motion.html#it">it</A> does change lines with only
white space!).

The <A HREF="options.html#'joinspaces'">'joinspaces'</A> option is used when lines are joined together.

You can set the <A HREF="options.html#'formatexpr'">'formatexpr'</A> option to an <A HREF="eval.html#expression">expression</A> or the <A HREF="options.html#'formatprg'">'formatprg'</A> option
to the name of an external program for Vim to use for text <A HREF="#formatting">formatting</A>.  The
<A HREF="options.html#'textwidth'">'textwidth'</A> and other <A HREF="options.html#options">options</A> have no effect on <A HREF="#formatting">formatting</A> by an external
program.


							*<A NAME="right-justify"></A><B>right-justify</B>*
There is no command in Vim to right justify text.  You can <A HREF="diff.html#do">do</A> <A HREF="motion.html#it">it</A> with
an external command, like &quot;par&quot; (e.g.: &quot;!}par&quot; to format until the end of the
<A HREF="motion.html#paragraph">paragraph</A>) or set <A HREF="options.html#'formatprg'">'formatprg'</A> to &quot;par&quot;.


							*<A NAME="format-comments"></A><B>format-comments</B>*
An overview of comment <A HREF="#formatting">formatting</A> is in section |<A HREF="usr_30.html#30.6">30.6</A>| of the user manual.

Vim can automatically insert and format comments in a special way.  Vim
recognizes a comment by a specific <A HREF="eval.html#string">string</A> at the start of the line (ignoring
white space).  Three types of comments can be used:

- A comment <A HREF="eval.html#string">string</A> that repeats at the start of each line.  An example is the
  type of comment used in shell scripts, starting with &quot;<A HREF="pattern.html##">#</A>&quot;.
- A comment <A HREF="eval.html#string">string</A> that occurs only in the first line, not in the following
  lines.  An example is this <A HREF="eval.html#list">list</A> with dashes.
- Three-piece comments that have a start <A HREF="eval.html#string">string</A>, an end <A HREF="eval.html#string">string</A>, and optional
  lines in between.  The strings for the start, middle and end are different.
  An example is the C style comment:
	/*
	 &#42; this is a C comment
	 */

The <A HREF="options.html#'comments'">'comments'</A> option is a comma-separated <A HREF="eval.html#list">list</A> of parts.  Each part defines a
type of comment <A HREF="eval.html#string">string</A>.  A part consists of:
	{flags}:{string}

{string} is the literal text that must appear.

{flags}:
  <A HREF="pattern.html#n">n</A>	Nested comment.  Nesting with mixed parts is allowed.  If <A HREF="options.html#'comments'">'comments'</A>
	is &quot;n:),n:&gt;&quot; a line starting with &quot;<A HREF="#&gt;">&gt;</A> ) &gt;&quot; is a comment.

  <A HREF="motion.html#b">b</A>	Blank (&lt;Space&gt;, <A HREF="motion.html#&lt;Tab&gt;">&lt;Tab&gt;</A> or <A HREF="intro.html#&lt;EOL&gt;">&lt;EOL&gt;</A>) required after {string}.

  <A HREF="motion.html#f">f</A>	Only the first line has the comment <A HREF="eval.html#string">string</A>.  Do not repeat comment on
	the next line, but preserve indentation (e.g., a bullet-list).

  <A HREF="#s">s</A>	Start of three-piece comment

  <A HREF="motion.html#m">m</A>	Middle of a three-piece comment

  <A HREF="motion.html#e">e</A>	End of a three-piece comment

  <A HREF="motion.html#l">l</A>	Left align. Used together with '<A HREF="#s">s</A>' or '<A HREF="motion.html#e">e</A>', the leftmost character of
	start or end will line up with the leftmost character from the middle.
	This is the default and can be omitted. See below for more details.

  <A HREF="#r">r</A>	Right align. Same <A HREF="motion.html#as">as</A> above but rightmost instead of leftmost. See
	below for more details.

  <A HREF="insert.html#O">O</A>	Don't consider this comment for the &quot;<A HREF="insert.html#O">O</A>&quot; command.

  <A HREF="#x">x</A>	Allows three-piece comments to be ended by just typing the last
	character of the end-comment <A HREF="eval.html#string">string</A> <A HREF="motion.html#as">as</A> the first action on a new
	line when the middle-comment <A HREF="eval.html#string">string</A> has been inserted automatically.
	See below for more details.

  {digits}
	When together with '<A HREF="#s">s</A>' or '<A HREF="motion.html#e">e</A>': add {digit} amount of offset to an
	automatically inserted middle or end comment leader. The offset begins
	from a left alignment. See below for more details.

  -{digits}
	Like {digits} but reduce the indent.  This only works when there is
	some indent for the start or end part that can be removed.

When a <A HREF="eval.html#string">string</A> has none of the '<A HREF="motion.html#f">f</A>', '<A HREF="#s">s</A>', '<A HREF="motion.html#m">m</A>' or '<A HREF="motion.html#e">e</A>' flags, Vim assumes the
comment <A HREF="eval.html#string">string</A> repeats at the start of each line.  The flags field may be
empty.

Any blank space in the text before and after the {string} is part of the
{string}, so <A HREF="diff.html#do">do</A> not include leading or trailing blanks unless the blanks are a
required part of the comment <A HREF="eval.html#string">string</A>.

When one comment leader is part of another, specify the part after the whole.
For example, to include both &quot;<A HREF="motion.html#-">-</A>&quot; and &quot;-&gt;&quot;, use
<B>	:set comments=f:-&gt;,f:-</B>

A three-piece comment must always be given <A HREF="motion.html#as">as</A> start,middle,end, with no other
parts in between.  An example of a three-piece comment is
<B>	sr:/*,mb:*,ex:*/</B>
for C-comments.  To avoid recognizing &quot;*ptr&quot; <A HREF="motion.html#as">as</A> a comment, the middle <A HREF="eval.html#string">string</A>
includes the '<A HREF="motion.html#b">b</A>' flag.  For three-piece comments, Vim checks the text after
the start and middle strings for the end <A HREF="eval.html#string">string</A>.  If Vim finds the end <A HREF="eval.html#string">string</A>,
the comment does not continue on the next line.  Three-piece comments must
have a middle <A HREF="eval.html#string">string</A> because otherwise Vim can't recognize the middle lines.

Notice the use of the &quot;<A HREF="#x">x</A>&quot; flag in the above three-piece comment definition.
When you hit Return in a C-comment, Vim will insert the middle comment leader
for the new line: &quot; &#42; &quot;.  To close this comment you just have to type &quot;<A HREF="pattern.html#/">/</A>&quot;
before typing anything else on the new line.  This will replace the
middle-comment leader with the end-comment leader and apply any specified
alignment, leaving just &quot; */&quot;.  There is no need to hit Backspace first.

When there is a match with a middle part, but there also is a matching end
part which is longer, the end part is used.  This makes a C style comment work
without requiring the middle part to end with a space.

Here is an example of alignment flags at work to make a comment stand out
(kind of looks like a 1 too). Consider comment <A HREF="eval.html#string">string</A>:
<B>	:set comments=sr:/***,m:**,ex-2:******/</B>
 
<B><FONT COLOR="PURPLE">                                   /*** </FONT></B>
<B><FONT COLOR="PURPLE">                                     **&lt;--right aligned from "r" flag </FONT></B>
<B><FONT COLOR="PURPLE">                                     ** </FONT></B>
<B><FONT COLOR="PURPLE">offset 2 spaces for the "-2" flag---&gt;** </FONT></B>
<B><FONT COLOR="PURPLE">                                   ******/ </FONT></B>
In this <A HREF="#case">case</A>, the first comment was typed, then return was pressed 4 times,
then &quot;<A HREF="pattern.html#/">/</A>&quot; was pressed to end the comment.

Here are some finer points of three part comments. There are three times when
alignment and offset flags are taken into consideration: opening a new line
after a start-comment, opening a new line before an end-comment, and
automatically ending a three-piece comment.  The end alignment flag has a
backwards perspective; the result is that the same alignment flag used with
&quot;<A HREF="#s">s</A>&quot; and &quot;<A HREF="motion.html#e">e</A>&quot; will result in the same indent for the starting and ending pieces.
Only one alignment per comment part is meant to be used, but an offset number
will override the &quot;<A HREF="#r">r</A>&quot; and &quot;<A HREF="motion.html#l">l</A>&quot; flag.

Enabling <A HREF="options.html#'cindent'">'cindent'</A> will override the alignment flags in many cases.
Reindenting using a different method like |<A HREF="#gq">gq</A>| or |<A HREF="#=">=</A>| will not consult
alignment flags either. The same behaviour can be defined in those other
<A HREF="#formatting">formatting</A> <A HREF="options.html#options">options</A>. One consideration is that <A HREF="options.html#'cindent'">'cindent'</A> has additional <A HREF="options.html#options">options</A>
for context based indenting of comments but cannot replicate many three piece
indent alignments.  However, <A HREF="options.html#'indentexpr'">'indentexpr'</A> has the ability to work better with
three piece comments.

Other examples:
<B>   "b:*"	Includes lines starting with "*", but not if the "*" is</B>
<B>		followed by a non-blank.  This avoids a pointer dereference</B>
<B>		like "*str" to be recognized as a comment.</B>
<B>   "n:&gt;"	Includes a line starting with "&gt;", "&gt;&gt;", "&gt;&gt;&gt;", etc.</B>
<B>   "fb:-"	Format a list that starts with "- ".</B>

By default, &quot;b:#&quot; is included.  This means that a line that starts with
&quot;#include&quot; is not recognized <A HREF="motion.html#as">as</A> a comment line.  But a line that starts with
&quot;<A HREF="pattern.html##">#</A> define&quot; is recognized.  This is a compromise.

You can use the <A HREF="options.html#'formatoptions'">'formatoptions'</A> option  to influence how Vim formats text.
<A HREF="options.html#'formatoptions'">'formatoptions'</A> is a <A HREF="eval.html#string">string</A> that can contain any of the letters below.  The
default setting is &quot;tcq&quot;.  You can separate the option letters with commas for
readability.

<B><FONT COLOR="PURPLE">letter	 meaning when present in 'formatoptions'    </FONT></B>

t	Auto-wrap text using textwidth
<A HREF="#c">c</A>	Auto-wrap comments using textwidth, <A HREF="insert.html#inserting">inserting</A> the current comment
	leader automatically.
<A HREF="#r">r</A>	Automatically insert the current comment leader after hitting
	<A HREF="intro.html#&lt;Enter&gt;">&lt;Enter&gt;</A> in <A HREF="insert.html#Insert">Insert</A> mode.
<A HREF="insert.html#o">o</A>	Automatically insert the current comment leader after hitting '<A HREF="insert.html#o">o</A>' or
	'<A HREF="insert.html#O">O</A>' in <A HREF="intro.html#Normal">Normal</A> mode.
<A HREF="repeat.html#q">q</A>	Allow <A HREF="#formatting">formatting</A> of comments with &quot;<A HREF="#gq">gq</A>&quot;.
	Note that <A HREF="#formatting">formatting</A> will not change blank lines or lines containing
	only the comment leader.  A new <A HREF="motion.html#paragraph">paragraph</A> starts after such a line,
	or when the comment leader changes.
<A HREF="motion.html#w">w</A>	Trailing white space indicates a <A HREF="motion.html#paragraph">paragraph</A> continues in the next line.
	A line that ends in a non-white character ends a <A HREF="motion.html#paragraph">paragraph</A>.
a	Automatic <A HREF="#formatting">formatting</A> of paragraphs.  Every time text is inserted or
	deleted the <A HREF="motion.html#paragraph">paragraph</A> will be reformatted.  See |<A HREF="#auto-format">auto-format</A>|.
	When the '<A HREF="#c">c</A>' flag is present this only happens for recognized
	comments.
<A HREF="pattern.html#n">n</A>	When <A HREF="#formatting">formatting</A> text, recognize numbered lists.  This actually uses
	the <A HREF="options.html#'formatlistpat'">'formatlistpat'</A> option, thus any kind of <A HREF="eval.html#list">list</A> can be used.  The
	indent of the text after the number is used for the next line.  The
	default is to find a number, optionally followed by '<A HREF="repeat.html#.">.</A>', '<A HREF="cmdline.html#:">:</A>', '<A HREF="motion.html#)">)</A>',
	'<A HREF="index.html#]">]</A>' or '<A HREF="motion.html#}">}</A>'.  Note that <A HREF="options.html#'autoindent'">'autoindent'</A> must be set too.  Doesn't work
	well together with &quot;2&quot;.
	Example:
<B>		1. the first item</B>
<B>		   wraps</B>
<B>		2. the second item</B>
2	When <A HREF="#formatting">formatting</A> text, use the indent of the second line of a <A HREF="motion.html#paragraph">paragraph</A>
	for the rest of the <A HREF="motion.html#paragraph">paragraph</A>, instead of the indent of the first
	line.  This supports paragraphs in which the first line has a
	different indent than the rest.  Note that <A HREF="options.html#'autoindent'">'autoindent'</A> must be set
	too.  Example:
<B>			first line of a paragraph</B>
<B>		second line of the same paragraph</B>
<B>		third line.</B>
 	This also works inside comments, ignoring the comment leader.
<A HREF="visual.html#v">v</A>	Vi-compatible auto-wrapping in insert mode: Only break a line at a
	blank that you have entered during the current insert command.  (Note:
	this is not 100&#37; <A HREF="intro.html#Vi">Vi</A> compatible.  <A HREF="intro.html#Vi">Vi</A> has some &quot;unexpected features&quot; or
	bugs in this area.  It uses the screen column instead of the line
	column.)
<A HREF="motion.html#b">b</A>	Like '<A HREF="visual.html#v">v</A>', but only auto-wrap if you enter a blank at or before
	the wrap margin.  If the line was longer than <A HREF="options.html#'textwidth'">'textwidth'</A> when you
	started the insert, or you <A HREF="diff.html#do">do</A> not enter a blank in the insert before
	reaching <A HREF="options.html#'textwidth'">'textwidth'</A>, Vim does not perform auto-wrapping.
<A HREF="motion.html#l">l</A>	Long lines are not broken in insert mode: When a line was longer than
	<A HREF="options.html#'textwidth'">'textwidth'</A> when the insert command started, Vim does not
	automatically format <A HREF="motion.html#it">it</A>.
<A HREF="motion.html#m">m</A>	Also break at a <A HREF="mbyte.html#multi-byte">multi-byte</A> character above 255.  This is useful for
	Asian text where every character is a <A HREF="motion.html#word">word</A> on its own.
<A HREF="motion.html#M">M</A>	When joining lines, don't insert a space before or after a <A HREF="mbyte.html#multi-byte">multi-byte</A>
	character.  Overrules the '<A HREF="motion.html#B">B</A>' flag.
<A HREF="motion.html#B">B</A>	When joining lines, don't insert a space between two <A HREF="mbyte.html#multi-byte">multi-byte</A>
	characters.  Overruled by the '<A HREF="motion.html#M">M</A>' flag.
1	Don't break a line after a one-letter <A HREF="motion.html#word">word</A>.  It's broken before <A HREF="motion.html#it">it</A>
	instead (if possible).
<A HREF="motion.html#j">j</A>	Where <A HREF="motion.html#it">it</A> makes sense, remove a comment leader when joining lines.  For
	example, joining:
<B><FONT COLOR="PURPLE">		int i;   // the index </FONT></B>
<B><FONT COLOR="PURPLE">		         // in the list </FONT></B>
	Becomes:
<B><FONT COLOR="PURPLE">		int i;   // the index in the list </FONT></B>


With '<A HREF="motion.html#t">t</A>' and '<A HREF="#c">c</A>' you can specify when Vim performs auto-wrapping:
<B><FONT COLOR="PURPLE">value	action	</FONT></B>
&quot;&quot;	no automatic <A HREF="#formatting">formatting</A> (you can use &quot;<A HREF="#gq">gq</A>&quot; for manual <A HREF="#formatting">formatting</A>)
&quot;<A HREF="motion.html#t">t</A>&quot;	automatic <A HREF="#formatting">formatting</A> of text, but not comments
&quot;<A HREF="#c">c</A>&quot;	automatic <A HREF="#formatting">formatting</A> for comments, but not text (good for C code)
&quot;tc&quot;	automatic <A HREF="#formatting">formatting</A> for text and comments

Note that when <A HREF="options.html#'textwidth'">'textwidth'</A> is 0, Vim does no automatic <A HREF="#formatting">formatting</A> anyway (but
does insert comment leaders according to the <A HREF="options.html#'comments'">'comments'</A> option).  An exception
is when the 'a' flag is present. |<A HREF="#auto-format">auto-format</A>|

Note that when <A HREF="options.html#'paste'">'paste'</A> is on, Vim does no <A HREF="#formatting">formatting</A> at all.

Note that <A HREF="options.html#'textwidth'">'textwidth'</A> can be non-zero even if Vim never performs auto-wrapping;
<A HREF="options.html#'textwidth'">'textwidth'</A> is still useful for <A HREF="#formatting">formatting</A> with &quot;<A HREF="#gq">gq</A>&quot;.

If the <A HREF="options.html#'comments'">'comments'</A> option includes &quot;/*&quot;, &quot;*&quot; and/or &quot;*/&quot;, then Vim has some
built in stuff to treat these types of comments a bit more cleverly.
Opening a new line before or after &quot;/*&quot; or &quot;*/&quot; (with '<A HREF="#r">r</A>' or '<A HREF="insert.html#o">o</A>' present in
<A HREF="options.html#'formatoptions'">'formatoptions'</A>) gives the correct start of the line automatically.  The same
happens with <A HREF="#formatting">formatting</A> and auto-wrapping.  Opening a line after a line
starting with &quot;/*&quot; or &quot;*&quot; and containing &quot;*/&quot;, will cause no comment leader to
be inserted, and the indent of the new line is taken from the line containing
the start of the comment.
E.g.:
<B><FONT COLOR="PURPLE">    /* </FONT></B>
<B><FONT COLOR="PURPLE">     * Your typical comment. </FONT></B>
<B><FONT COLOR="PURPLE">     */ </FONT></B>
    The indent on this line is the same <A HREF="motion.html#as">as</A> the start of the above
    comment.

All of this should be really cool, especially in conjunction with the new
<A HREF="autocmd.html#:autocmd">:autocmd</A> command to prepare different settings for different types of file.

Some examples:
  for C code (only format comments):
<B>	:set fo=croq</B>
  for Mail/news	(format all, don't start comment with &quot;<A HREF="insert.html#o">o</A>&quot; command):
<B>	:set fo=tcrq</B>
 


Automatic <A HREF="#formatting">formatting</A>				*<A NAME="auto-format"></A><B>auto-format</B>* *<A NAME="autoformat"></A><B>autoformat</B>*

When the '<A HREF="insert.html#a">a</A>' flag is present in <A HREF="options.html#'formatoptions'">'formatoptions'</A> text is formatted
automatically when <A HREF="insert.html#inserting">inserting</A> text or <A HREF="#deleting">deleting</A> text.  This works <A HREF="todo.html#nice">nice</A> for
editing text paragraphs.  A few hints on how to use this:

- You need to properly define paragraphs.  The simplest is paragraphs that are
  separated by a blank line.  When there is no separating blank line, consider
  using the '<A HREF="motion.html#w">w</A>' flag and adding a space at the end of each line in the
  paragraphs except the last one.

- You can set the <A HREF="options.html#'formatoptions'">'formatoptions'</A> based on the type of file |<A HREF="filetype.html#filetype">filetype</A>| or
  specifically for one file with a |<A HREF="options.html#modeline">modeline</A>|.

- Set <A HREF="options.html#'formatoptions'">'formatoptions'</A> to &quot;aw2tq&quot; to make text with indents like this:

	    bla bla foobar bla 
	bla foobar bla foobar bla
	    bla bla foobar bla 
	bla foobar bla bla foobar

- Add the '<A HREF="#c">c</A>' flag to only <A HREF="#auto-format">auto-format</A> comments.  Useful in source code.

- Set <A HREF="options.html#'textwidth'">'textwidth'</A> to the desired width.  If <A HREF="motion.html#it">it</A> is zero then 79 is used, or the
  width of the screen if this is smaller.

And a few warnings:

- When part of the text is not properly separated in paragraphs, making
  changes in this text will cause <A HREF="motion.html#it">it</A> to be formatted anyway.  Consider doing

<B>	:set fo-=a</B>

- When using the '<A HREF="motion.html#w">w</A>' flag (trailing space means <A HREF="motion.html#paragraph">paragraph</A> continues) and
  <A HREF="#deleting">deleting</A> the last line of a <A HREF="motion.html#paragraph">paragraph</A> with |<A HREF="#dd">dd</A>|, the <A HREF="motion.html#paragraph">paragraph</A> will be
  joined with the next one.

- Changed text is saved for <A HREF="undo.html#undo">undo</A>.  Formatting is also a change.  Thus each
  format action saves text for <A HREF="undo.html#undo">undo</A>.  This may consume quite a lot of memory.

- Formatting a long <A HREF="motion.html#paragraph">paragraph</A> and/or with complicated indenting may be slow.

==============================================================================

7. Sorting text						*<A NAME="sorting"></A><B>sorting</B>*

Vim has a <A HREF="#sorting">sorting</A> function and a <A HREF="#sorting">sorting</A> command.  The <A HREF="#sorting">sorting</A> function can be
found here: |<A HREF="eval.html#sort()">sort()</A>|, |<A HREF="eval.html#uniq()">uniq()</A>|.


							*<A NAME=":sor"></A><B>:sor</B>* *<A NAME=":sort"></A><B>:sort</B>*
:[range]sor[t][!] [b][f][i][n][o][r][u][x] [/{pattern}/]
			Sort lines in <A HREF="cmdline.html#[range]">[range]</A>.  When no range is given all
			lines are sorted.

			With [!] the order is reversed.

			With [i] <A HREF="#case">case</A> is ignored.

			Options [n][f][x][o][b] are mutually <A HREF="motion.html#exclusive">exclusive</A>.

			With [n] <A HREF="#sorting">sorting</A> is done on the first decimal number
			in the line (after or inside a {pattern} match).
			One leading '<A HREF="motion.html#-">-</A>' is included in the number.

			With [f] <A HREF="#sorting">sorting</A> is done on the <A HREF="eval.html#Float">Float</A> in the line.
			The value of <A HREF="eval.html#Float">Float</A> is determined similar to passing
			the text (after or inside a {pattern} match) to
			<A HREF="eval.html#str2float()">str2float()</A> function. This option is available only
			if Vim was compiled with Floating point support.

			With [x] <A HREF="#sorting">sorting</A> is done on the first hexadecimal
			number in the line (after or inside a {pattern}
			match).  A leading &quot;0x&quot; or &quot;0X&quot; is ignored.
			One leading '<A HREF="motion.html#-">-</A>' is included in the number.

			With [o] <A HREF="#sorting">sorting</A> is done on the first <A HREF="eval.html#octal">octal</A> number in
			the line (after or inside a {pattern} match).

			With [b] <A HREF="#sorting">sorting</A> is done on the first binary number in
			the line (after or inside a {pattern} match).

			With [u] (u stands for unique) only keep the first of
			a sequence of identical lines (ignoring <A HREF="#case">case</A> when [i]
			is used).  Without this flag, a sequence of identical
			lines will be kept in their original order.
			Note that leading and trailing white space may cause
			lines to be different.

			When /{pattern}/ is specified and there is no [r] flag
			the text matched with {pattern} is skipped, so that
			you sort on what comes after the match.
			Instead of the slash any non-letter can be used.
			For example, to sort on the second comma-separated
			field:
<B>				:sort /[^,]*,/</B>
 			To sort on the text at virtual column 10 (thus
			ignoring the difference between tabs and spaces):
<B>				:sort /.*\%10v/</B>
 			To sort on the first number in the line, no matter
			what is in front of <A HREF="motion.html#it">it</A>:
<B>				:sort /.\{-}\ze\d/</B>
 			(Explanation: &quot;.\{-}&quot; matches any text, &quot;\ze&quot; sets the
			end of the match and \d matches a digit.)
			With [r] <A HREF="#sorting">sorting</A> is done on the matching {pattern}
			instead of skipping past <A HREF="motion.html#it">it</A> <A HREF="motion.html#as">as</A> described above.
			For example, to sort on only the first three letters
			of each line:
<B>				:sort /\a\a\a/ r</B>

 			If a {pattern} is used, any lines which don't have a
			match for {pattern} are kept in their current order,
			but separate from the lines which <A HREF="diff.html#do">do</A> match {pattern}.
			If you sorted in reverse, they will be in reverse
			order after the sorted lines, otherwise they will be
			in their original order, right before the sorted
			lines.

			If {pattern} is empty (e.g. <A HREF="version7.html#//">//</A> is specified), the
			last search <A HREF="pattern.html#pattern">pattern</A> is used.  This allows trying out
			a <A HREF="pattern.html#pattern">pattern</A> first.

Note that using `:sort` with `:global` doesn't sort the matching lines, it's
quite useless.

The details about <A HREF="#sorting">sorting</A> depend on the library function used.  There is no
guarantee that <A HREF="#sorting">sorting</A> obeys the current <A HREF="mbyte.html#locale">locale</A>.  You will have to try <A HREF="motion.html#it">it</A> out.
Vim does <A HREF="diff.html#do">do</A> a &quot;stable&quot; sort.

The <A HREF="#sorting">sorting</A> can be interrupted, but if you interrupt <A HREF="motion.html#it">it</A> too late in the
process you may end up with duplicated lines.  This also depends on the system
library function used.
