Lightweight and works like a charm. You have to manually rehash the list if you add programs or documents, but that's an easy click to do. I do wish the hotkey was a little more flexible (I'd rather do CMD-OPT-F1 for single-hand operation...CMD-F1 is already used by another app). My only other request is to be able to assign separate hotkeys: one for apps and one for documents. Bottom line is that it works, it's smooth, and it's FREE!
