Ok, I have a feelling I'm missing something very basic here, but I got my new wireless aluminum keyboard yesterday and though I love it, I can't get the Functions keys to work properly. There are little icons above some of the F keys to control volume, brightness, expose, etc. but how do you make the key do that? I've tried hitting the Fn key, the command key, the Alt key, the shift key, all in combination with the F keys....it always does the same thing as if I had only hit the F key (for example, my F12 brings up Dashboard, but according to the little icon, it should also control volume. How do I use the volume control? ) I'm sure I'll feel dumb when someone gives me the answer. Running with a Core Duo iMac that is nearly 2 years old. thanks!
