Keytweak: A Keyboard Remapping Program
Keytweak is a useful piece of software. It lets you remap your computer keyboard, so that you could, for example, make the “a” key print out “e” whenever it is typed. That’s not useful (though you could program in the Dvorak keyboard if you wanted), but what I like is to get rid of the deplorable CAPS LOCK key. Keytweak lets you turn it into a harmless extra SHIFT key.
