How do I use function keys on a Mac?

I recently switched my whole system to Mac OSX (Snow Leopard 10.6) from Windows 7. Now I've installed WoW and imported my old configs/addons without any problems, besides that my keybindings from F1 to F7 are completely overriden by some Mac functions like brightness/sound/keyboard backlight etc.

How can I use my F-Keys in games?


Solution 1:

The option you want is in the Keyboard pane of your System Preferences:

Unfortunately this applies to all applications, not just WoW, which is kind of a pain because almost no other Mac OS X apps use the function keys for anything.

Solution 2:

Use Option + Function-Key for the F1-F10 on Mac OS X.

Solution 3:

For me it is fn + shift in Mac OS X v10.6.8.
