There is a mac application called Shortcat and it make me envious.
For those of you averse to clicking links here is a summary:
Keep your hands on the keyboard and boost your productivity! Shortcat is a keyboard tool for Mac OS X that lets you "click" buttons and control your apps with a few keystrokes. Think of it as Spotlight for the user interface.
So basically it lets you search within a GUI application. As I prefer typing for things than looking for things it sounds quite useful. I will probably be dreaming about this tonight.. and maybe looking for APIs to make it possible tomorrow. Unless of course...
there an equivelant available for gnome?
