The lifehacker has a very nice post on how to get more out of Launchy. In case you don’t know what Launchy is:

Launchy is a free windows utility designed to help you forget about your start menu, the icons on your desktop, and even your file manager.

Launchy indexes the programs in your start menu and can launch your documents, project files, folders, and bookmarks with just a few keystrokes!
