Here's a couple of little things I have in my Free Nodelet for quickly searching for stuff in site code. The first is a link which searches immediately for the title of the current node - particularly useful if the current node is a htmlcode or something like that. The second is a form just like the one in Search internal code, but with no controls and no submit button; just hit <Enter> to submit the search (at least in most modern, sane browsers).

<a href="/?node_id=157620;searchterms=`title%`">Search for <i>`title&`
+</i> in code</a>

<br/>

<form method="post" action="?" enctype="application/x-www-form-urlenco
+ded">
Search PM code:
<input type="text" name="searchterms" size="40" id="codesearch">
<input type="hidden" name="node_id" value="157620">
<input type="hidden" name="sexisgood" value="submit">
</form>
