<p>
 The autocompleting search feature is accessible via the form elements at the top
 right of php.net pages. 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>
 If you are not interested in this feature, you can turn it
 off for yourself on the <a href="/my.php">My PHP.net</a> page.
</p>
<p>
 In case you find any bugs, <a href="http://bugs.php.net/">we are interested</a>
 in a detailed writeup, including JS error messages, operating system and browser
 information. The source code of this feature is released under the PHP License and
 is available <a href="http://svn.php.net/phpdoc/doc-base/trunk/scripts/quickref">from the
 PHP SVN server</a> without any support.
