ALANR For $20 I'd recommend that people also look at Keyboard Maestro. It's a commercial program for the same price with many more features. (Version 2.0.8)
ANONYMOUS The previous review has no bearing on reality.
Maybe the person tried to use it for a few minutes, misunderstood some aspect, and gave up right away. I have used this app for a year ... it is a no brainer ... a snap to setup and edit ... and works flawlessly. (Version 2.0fc1)
JACK This app has a lot of flaws. It works only sporadically. In addition it changed a couple of the keys on my keyboard, so that whenever I type "a" it prints "q" and vice-versa. I don't think this is ready for even a beta version. Lots of work to do yet. (Version 2.0b6)
