"This week, I've been experimenting with gnome-do, the Gnome application launcher that also allows you to specify particular actions to take on whatever file or application you've found. Very much like Quicksilver on the Mac, for anyone who's familiar with that.
"Once installed and started up, you can hit Windows-Space to summon the app launcher (this is configurable). Start typing, and gnome-do will start searching through various places for something that matches what's typed. You can scroll through match options with the arrow keys, or hit ESC to cancel."
