Launchy

Here's another awesome freeware mentioned on Bnet:

When I want to run, say, Excel, I hit Alt-Space, type “Exc,” and hit Enter — a process that takes me about two seconds. Contrast that with searching the desktop, Start menu, etc. for the Excel icon and you’ll see why I love this launcher. Anything that keeps me from having to reach for the mouse is worth its weight in gold (even if it is just code).

You can find it at http://www.launchy.net/. It's fun!!
