CEMACSOFT I have tried to force myself to use a competitor application for years (didn’t know of QuicKeys till very recently), and ended up with a couple of poor macros that sometimes worked...
I have discovered QuicKeys X just two weeks ago, and I already have 20 complex reliable macros that I use many times a day. There are some features that I'd like to see to facilitate the organization (i.e. folders for shortcuts and abbreviations), but the application is simply outstanding. It's not cheap, but given the amount time it can save I have already placed my pre-order.
