Keyboard shortcut to open new Tab in Terminal.app

Hi,

I'm looking for a way to open new tabs with keyboard shortcuts in Terminal.app

Opening the default profile is not a problem (command-T), but how can I get to the non-default profiles? Assigning keyboard shortcuts in the System Preferences doesn't seem to work.

Maybe something like a Quicksilver Trigger? Applescript? Any ideas?

Thanks,
Koinseb
