Suddenly, today, my fn key stopped working. Nothing happens when I hit fn + any of the function keys at the top of the keyboard -- except when I'm running Firefox and I hit fn + f3, which opens the find tool.
Not long before I noticed this problem, I'd run a sudo rm -rf command in Terminal to get rid of something that wouldn't be deleted because it was "in use". Could that have affected my fn key at all? That's the only thing I'd done that was out of the ordinary...

EDIT: I figured it out! Somehow the option to enable use of the f keys got unchecked. Sorry for the trouble!
