Hi all,
I put together a [CTags.tmbundle][1] for easy double-click installation in recent (cutting edge) TextMate versions. The CTags bundle allows you to quickly look up function definitions, variables etc. It uses the Exuberant CTags program to generate a list of definitions, and presents any match for the current word when invoked.
Allan, if you give me access to the bundle repository I'll gladly submit and maintain this bundle.
