As I need to use the fn + F8 shortcut within my virtual machine, I'd like to disable it in my host.

How do I go about disabling this particular shortcut, so that it can be used within my VM?

Does fn-F8 mean the normal F8 key or a symbolic hotkey or media key under F8? In the latter case, see Documenting - The macosxhints Forums. – ؘؘؘؘ Sep 23 '11 at 13:47

Special keys (like brightnes, volume and playing controls) are not configurable via the Keyboard prefpane – mspasov Jun 24 '11 at 13:14
fn f8 is available there on my laptop (spaces). I unchecked the use all f1,f2,f3 keys as standard functions under keyboard in system preferences, maybe that's the cause. – Tim Jun 24 '11 at 13:18

In addition to KeyRemap4MacBook, there is also DoubleCommand (free and open source).
