 The autocompleting search feature is accessible via the form elements at the top
 right of this page. You should be able to use this feature in a reasonably modern
 browser by selecting the 'function list' search option and typing in some letters
 into the searchbox. Features:
</p>
<ul>
 <li>Dynamically changing list of function names starting with the substring you typed</li>
 <li>Navigate in the list with up and down keys</li>
 <li>Autocomplete with pressing the space key</li>
 <li>Go to a function by clicking on its name with your mouse</li>
</ul>
<p>
 We are interested in detailed bug reports including JS error messages, operating system
 and browser information. We are planning on deploying this feature to all PHP.net pages
 if we can manage to make it work without errors for most of the comonly used browsers.
</p>
<p>
 The source code of this feature is released under the PHP License and is available
 <a href="http://cvs.php.net/cvs.php/phpdoc/scripts/quickref">from the PHP CVS server</a>
 without any support.
