Just as of 20 minutes ago, I was able to type, but then for no reason, my computer can't type. The strange thing is that when I use the control click, use the mouse, or use the f keys, it works just fine. I used onyx to clean my computer, which didn't work. I restarted my computer, which didn't work, and I tried to go into the Keyboard/Mouse panel, but then System Preferences quit for no reason. I really need help right now because I can't be on my computer because of this crap.
