How do I get my function keys to do their stuff within programs? For instance, in Quark F6 should unlock or lock boxes, F7 should show or hide guides; in Word F7 should spellcheck - and so on. Neither these nor the normal shortcuts (ctrl-mouse = zoom in Quark) are working. I'm sure there must be some way to free the keys. Anyone know? I've looked in the Keyboard controls in System Prefs, but not a dicky-bird.
