I'd love to learn that there's a way to get this to work in all  
cases, but I've only found Ctrl+C to work when the script is directly  
invoked by a "Command". Things like backtick shell expansions in  
snippets don't appear to be listening...

I hadn't realized there would be much controversy that this was an  
opportunity for improvement in TextMate's architecture. Is there a  
way to cancel any kind of shell command spawned by the application?

Am I also the only one annoyed by the current Undo implementation?
