I felt obliged to offer my review -- after being a QuicKeys user since 1992 or so -- to try to counterbalance the unfathomable negative reviews. There can be no mere "difference of opinion," and chowhound is correct: those unfairly posting low ratings have either a) not actually used the software, b) not the mental capacity to use the software, or c) an agenda.

I currently have 406 shortcuts established. Many of those are tied to keystrokes. Many are set to trigger at a particular time, or after a particular event (whenever the Music volume mounts run a sync of my iTunes Library files -- easy to set up, in case you're wondering), and many are set to work only within the scope of a particular application (determine what "Cmd-Shift-S" does on a per-application basis), etc.

It's indispensable, insanely powerful, and absurdly easy considering the power you're harnessing.

Buy it. Play with it. If you're still not sure, RTFM (though you will likely not need to until/unless you want the more advanced stuff.)

Quicksilver's great. It's *not* a replacement. I use them both, and Quicksilver *only* for very specific things (such as it's ability to chain events and perhaps show me a dialog of a custom message after a particular delay.)

Otherwise, it's QuicKeys 250 times a day for me. Sitting at a computer that does not have QuicKeys (and more specifically my shortcuts) installed makes me wonder how I could possibly get along without it. It's that good and that indispensable.

10 stars, no joke.
