Find and Run Robot (FARR) is a program for keyboard maniacs -- it uses an adaptive "live search" function to rapidly find programs and documents on your computer as you type. Press your chosen hotkey to display the FARR window, then just start typing the first letters of the application you want to launch and the results appear instantly. Hit enter to launch the top result, or refine your search with special modifiers and commands. - Morton Fox

And plugins to do all sorts of other things! - April Russo (app103)
