Hello. Just got my new MacPro. It seems I have a conflict using Quark. In Quark, the F7 key brings up guides. However, the default F7 key is for audio (itunes). I went to System Preferences > Keyboard, and checked "Use all F1, F2, etc..." and now the Quark default key works, but the audio does not. Is there a way to change the key default? Or allow Quark to override the itunes? It appears I can use one or the other. Thanks.
