I have a USB Apple© keyboard, and several weeks ago, possibly a month or two by now, the "left" and "down" keys just stopped working. I have restarted my computer many times and for many different reasons, and that obviously has not worked. If anyone can tell me maybe up to take the keys off and maybe see if i can do anything by doing that, or if anyone has any tip on anything i can do, that would be greatly appreciated. However, if not, its not a big deal and thanks for the help.
