On many newer keyboards, the F keys do double duty. Put the F-Lock switch on
and you get the standard F-key behavior. Turn the F-Key switch off and the
keys are redefined (badly so, in my opinion) to other functions. The F-Lock
key is probably just to the right of your F12 key and it probably toggles an
LED on the keyboard on and off indicating status.
