I am using Mac OS X and have got one of those new flat keyboards today. This is it. http://cache.gizmodo.com/assets/resources/2007/07/imac-slim-keyboard-1.jpg I want to know how to use the F keys though. To use the volume keys and the play/pause keys. I have went to system preferences and tried unchecking the boxes for F9-F12 but it doesn't seem to be working. How can I use these keys? Any shortcuts for them? Any help please. Thanks.
