<h3 class="section">3.2 The Status Bar</h3>
<p><a name="index-Status-bar-58"></a><a name="index-Line-and-column-numbers-59"></a><a name="index-Fast-GUI-60"></a>
The last line of the screen, the <dfn>status bar</dfn>, is reserved by
<code>ne</code> for displaying some information about its internal state.
Note that on most terminals it is physically impossible to write a
character on the last column of the last line, so we are not
stealing precious editing space.
<p>The status bar looks more or less like this:
<pre class="example"> L: 31 C: 25 12% iabcwfpvurtBMRPC*@8 20 /foo/bar
</pre>
<p>The numbers after ‘<samp><span class="samp">L:</span></samp>’ and ‘<samp><span class="samp">C:</span></samp>’ are the line and column of the
cursor position. The first line and the first column are both number
1. Then, <code>ne</code> shows the percentage of lines before the current line
(it will be 0% on the first line, and 100% on the last line).
<p>Following that are a sequence of letters or
dashes. These indicate the status of a series of flags which we shall
look at later.
<p>The hexadecimal digits following the flags give the code for the
character at the cursor, and are displayed optionally (see <a href="HexCode.html#HexCode">HexCode</a>).
If your cursor is at or beyond the right end of the current line, the
code disappears.
<p>The file name appearing after the character code is the file name of
the current document. The left end of very long file names may be
truncated to keep the right end visible. Of course,
<code>ne</code> is keeping track internally of the complete file name. It
is used by the <code>Save</code> command and as the default input for the
<code>SaveAs</code> command. See <a href="Save.html#Save">Save</a>, and <a href="SaveAs.html#SaveAs">SaveAs</a>.
<p>The displayed line and column numbers, the percentage indicator and the
character code change when the cursor moves. This fact can really slow
down cursor movement if you are using <code>ne</code> through a slow
connection. If you find this to be a problem, it is a good idea to turn
off the status bar using either the ‘<samp><span class="samp">Status Bar</span></samp>’ menu item of the
‘<samp><span class="samp">Prefs</span></samp>’ menu or the <code>StatusBar</code>
command. See <a href="StatusBar.html#StatusBar">StatusBar</a>. Alternatively you can turn on the fast GUI
mode using either the ‘<samp><span class="samp">Fast GUI</span></samp>’ menu item of the ‘<samp><span class="samp">Prefs</span></samp>’ menu
or the <code>FastGUI</code> command (see <a href="FastGUI.html#FastGUI">FastGUI</a>). In fast GUI mode the
status bar is not draw in reverse, so some additional optimization can
be done when refreshing it.
<p>The letters after the line and column number represent the status of the flags
associated with the current document. Flags that are off display a
‘<samp><span class="samp">-</span></samp>’ instead of a letter. Each flag also has an
associated command. The <code>Flags</code> command describes them all when
you don't have this manual handy. Here's the list in detail:
<dl>
<dt>‘<samp><span class="samp">i</span></samp>’<dd>appears if the insert flag is true. See <a href="Insert.html#Insert">Insert</a>.
<br><dt>‘<samp><span class="samp">a</span></samp>’<dd>appears if the auto indent flag is true. See <a href="AutoIndent.html#AutoIndent">AutoIndent</a>.
<br><dt>‘<samp><span class="samp">b</span></samp>’<dd>appears if the back search flag is true. See <a href="SearchBack.html#SearchBack">SearchBack</a>.
<br><dt>‘<samp><span class="samp">c</span></samp>’<dd>appears if the case sensitive search flag is true. See <a href="CaseSearch.html#CaseSearch">CaseSearch</a>.
<br><dt>‘<samp><span class="samp">w</span></samp>’<dd>appears if the word wrap flag is true. See <a href="WordWrap.html#WordWrap">WordWrap</a>.
<br><dt>‘<samp><span class="samp">f</span></samp>’<dd>appears if the free form flag is true. See <a href="FreeForm.html#FreeForm">FreeForm</a>.
<br><dt>‘<samp><span class="samp">p</span></samp>’<dd>appears if the automatic preferences flag is true. See <a href="AutoPrefs.html#AutoPrefs">AutoPrefs</a>.
<br><dt>‘<samp><span class="samp">v</span></samp>’<dd>appears if the verbose macros flag is true. See <a href="VerboseMacros.html#VerboseMacros">VerboseMacros</a>.
<br><dt>‘<samp><span class="samp">u</span></samp>’<dd>appears if the undo flag is true. See <a href="DoUndo.html#DoUndo">DoUndo</a>.
<br><dt>‘<samp><span class="samp">r</span></samp>’<dd>appears if the read only flag is true. See <a href="ReadOnly.html#ReadOnly">ReadOnly</a>.
<br><dt>‘<samp><span class="samp">t/T</span></samp>’<dd>appears as ‘<samp><span class="samp">t</span></samp>’ if the tabs flag is true, ‘<samp><span class="samp">T</span></samp>’ if
the shifttabs flag is also true. See <a href="Tabs.html#Tabs">Tabs</a>, <a href="ShiftTabs.html#ShiftTabs">ShiftTabs</a>.
<br><dt>‘<samp><span class="samp">d</span></samp>’<dd>appears if the deltabs flag is true. See <a href="DelTabs.html#DelTabs">DelTabs</a>.
<br><dt>‘<samp><span class="samp">B</span></samp>’<dd>appears if the binary flag is true. See <a href="Binary.html#Binary">Binary</a>.
<br><dt>‘<samp><span class="samp">M</span></samp>’<dd>appears if you are currently marking a block. See <a href="Mark.html#Mark">Mark</a>.
<br><dt>‘<samp><span class="samp">V</span></samp>’<dd>can appear in place of ‘<samp><span class="samp">M</span></samp>’ if you are currently marking a vertical
block. See <a href="MarkVert.html#MarkVert">MarkVert</a>.
<br><dt>‘<samp><span class="samp">R</span></samp>’<dd>appears if you are currently recording a macro. See <a href="Record.html#Record">Record</a>.
<br><dt>‘<samp><span class="samp">P</span></samp>’<dd>appears if the PreserveCR flag is true. See <a href="PreserveCR.html#PreserveCR">PreserveCR</a>.
<br><dt>‘<samp><span class="samp">C</span></samp>’<dd>appears if the CRLF flag is true. See <a href="CRLF.html#CRLF">CRLF</a>.
<br><dt>‘<samp><span class="samp">*</span></samp>’<dd>appears if the document has been modified since the last save, or if
the <code>Modified</code> command was issued to set this flag. See <a href="Modified.html#Modified">Modified</a>.
<br><dt>‘<samp><span class="samp">@</span></samp>’<dd>appears if UTF-8 I/O is enabled. See <a href="UTF8IO.html#UTF8IO">UTF8IO</a>.
<br><dt>‘<samp><span class="samp">A/8/U</span></samp>’<dd>denotes the current buffer encoding—US-ASCII, 8-bit or UTF-8. See <a href="UTF8.html#UTF8">UTF8</a>.
</dl>
<p>Note that sometimes <code>ne</code> needs to communicate some message to you. The
message is usually written over the status bar, where it stays
until you do something. Any action such as moving the cursor or inserting a
character will restore the normal status bar.
