<h3 class="section">E.5 Using <code>occur</code></h3>
<a name="index-Occurrences_002c-listing-with-_0040occur"></a>
<a name="index-occur"></a>
<p>Sometimes the <code>texinfo-show-structure</code> command produces too much
information. Perhaps you want to remind yourself of the overall structure
of a Texinfo file, and are overwhelmed by the detailed list produced by
<code>texinfo-show-structure</code>. In this case, you can use the <code>occur</code>
command directly. To do this, type:
</p>
<div class="example">
<pre class="example"><kbd>M-x occur</kbd>
</pre></div>
<p>and then, when prompted, type a <em>regexp</em>, a regular expression for
the pattern you want to match. (See <a href="http://www.gnu.org/software/emacs/manual/html_node/emacs/Regexps.html#Regexps">Regular Expressions</a> in <cite>The GNU Emacs Manual</cite>.) The <code>occur</code> command works from
the current location of the cursor in the buffer to the end of the
buffer. If you want to run <code>occur</code> on the whole buffer, place
the cursor at the beginning of the buffer.
</p>
<p>For example, to see all the lines that contain the word
‘<samp>@chapter</samp>’ in them, just type ‘<samp>@chapter</samp>’. This will
produce a list of the chapters. It will also list all the sentences
with ‘<samp>@chapter</samp>’ in the middle of the line.
</p>
<p>If you want to see only those lines that start with the word
‘<samp>@chapter</samp>’, type ‘<samp>^@chapter</samp>’ when prompted by
<code>occur</code>. If you want to see all the lines that end with a word
or phrase, end the last word with a ‘<samp>$</samp>’; for example,
‘<samp>catching mistakes$</samp>’. This can be helpful when you want to see
all the nodes that are part of the same chapter or section and
therefore have the same ‘Up’ pointer.
</p>
