I've tried that too. Tried all the F1 keys in conjunction with the function key, and also tried every key on the keyboard that has blue on it. Nothing works! There's GOT to be a toggle key combination for this.
ANYONE know HOW I can get an answer to this? It's been days and I really need to get it fixed!!! There really ought to be a manual for key combinations for this computer/keyboard, but I find nothing in the control panel or in Help and support.
So frustrating that an answer to something like this can't be found
