Like my friend Gregory, I used LaunchBar but never got hooked on it. His post on Quicksilver as an alternative to LaunchBar intrigued me, so I installed it. With just a few keystrokes, I have the ability to browse just about anything I want on my laptop, including my iTunes library, address book entries, bookmarks, plus a robust clipboard and a “shelf” that I haven’t figured out how to properly use yet. Hooray for Quicksilver!
Edit: This is Panther-only software. (Sorry, Torq.)
