Knowing keyboard shortcuts is probably one of the most useful things you can learn. Not only will it simplify your workflow but it's also a way of getting to know the programs you have. We were impressed with the number of features available in Keyboard Maestro. The program lets you create all sorts of keyboard shortcuts, which you can easily cut and paste and apply to other actions.

The Program and Application Switcher windows turn out to be really handy to quickly access your most used programs and folders. We also liked how you can dig into particular programs like iTunes and set actions like play, pause or create playlists.

The only real worry we had with Keyboard Maestro is overusing it. If you create too many keyboard shortcuts you'll have to make sure you can remember them all. In this sense, we only recommend using this program if you already feel comfortable with your Mac and are looking for a way of cutting corners.
