Let's say there's something like "require 'shared/session.inc.php';" in my code. Now I'd like to move the cursor above the filename, press any shortcut, and - voilà - TextMate opens the file.

The PHP bundle includes a “Jump to Included File” command which can do this, in fact if you configure your PHP include path then it can even search for the file in there.

Check out the bundle help – from Bundles → PHP → Help – for more info.
