So basically, my down arrow key popped off and I don't have time to go the Apple store for the next couple of weeks. I'm looking for some application that will let me set a key (or multitude of keys) to replace down. I tried looking online, but I could only find applications that let you launch applications or whatnot with shortcuts, but not just replace another key. Thanks. Update: Well after looking even more, I found that Keyboard Maestro does what I want.
