I found this site that has the code for readkey for Windows, Unix, and in an updated version, Mac: http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/134892 . The Mac object returns a character whether or not a key was pressed. I modified the Windows object to do the same when I downloaded it, but I have no idea how to make the Unix object instantly return either the character or an empty string. Any help???
