Currently, I have ported ctags to dreamweaver.

http://dwoop.googlecode.com/svn/trunk/images/dwoop01.png'> You can double click a function/class name to select it, then right click, in the contenxt menu, select 'Go To Definition...'.

Before you can go to definition, you have to create the ctags tag file first, which is a hidden file located in the main directory of the site. You do it by click the 'site' menu then, click 'Create Tags File...'. This will create a hidden file named 'dwoop' in the main directory of your site. This file contains all the location information of tags for your site(only PHP's class,interface,function now)

If you modify and save any PHP source code files, dwoop will reparse the file automatically.

If you encounter the error: 'Cannot update Toolbars.xml'. It's a bug of Dreamweaver. You can safely delete it and Dreamweaver will automatically recreate the file when you next launch. The file located in 'C:\Documents and Settings{your user name}\Application Data\adobe\Dreamweaver CS4\en_US\Configuration\Toolbars'
