The iMac overrides the default functionality for the function keys. This can be reverted though, but thats not what I want.
They Keyboard Viewer doesnt also really help me, since the working keys, F4 for example, dont get highlighted when pressed... Bummer.
I have an iMac with the extended new keyboard. The 3 first Fx buttons stopped working after a while. I don't know if they are damaged or if they are simply disabled. Can I verify this somehow? In the settings or something.
F1 and F2 were used to handle the screen brightness and F3 was for expose.
Hm, ok. I unchecked the "Turn on full keyboard access" and then rechecked it. Now it also works fine in the everywhere. Weird.
Anyway, me happy now. Thanks for the help.
