I used this for awhile and was really keen on it - especially the Clock and Volume visual-display plugins, for which I've found no equivalent among other hotkey programs. But I stopped using it this week, because I found that it was hogging the keyboard hook that allows Google Desktop Search 3's neat Quick Search Box, and frankly I would rather have that than HotKeys, especially since TrueLaunchBar can give me all the hotkeys I need.
