I have been using Launchy for a long time. It is a very good keystroke launcher, a best tool for keyboard fanatic. However, it takes too much ram on my Win7 machine and keeps crashing constantly. After googling a while, I found [FARR]("The Ultimate Program for Keyboard Maniacs") (Find and Run Robot), a highly configurable, full-featured keystroke launcher which brands itself as "The Ultimate Program for Keyboard Maniacs". This one is less eye-candy than Launchy but definitely a tool for a fanatic. It sports regular expression matching with customizable scoring. Best of all, it takes only a minimal amount of ram.
