My Keyboard Won't Type! Why did my cat have to lay on it?Cats are wonderful, but sometimes they jump on our keyboards and we can't figure out what buttons they pushed.
Solution 1:Restart your computer. This usually takes care of keyboard problems, but you could lose data.
Solution 2:Your cat may have turned on "mouse keys". If you push s or c from the log-in screen, you'll notice that these might be the only keys that work. "c" will take you to the screensaver and "s" will bring up the sleep, restart, shutdown menu.
To fix this, just press "ALT + M" at the same time. Now you can type again!
