On my MacBook I have use all F1 F2 etc. keys as standard function keys option unchecked. I use FunctionFlip to map F3 from Expose to Spaces.
However I would like to use function keys as real function keys when working under virtualised environment like VirtualBox or VMware Fusion. Going to System > Preferences is not very convenient.
Do you now how to check use all F1 F2 etc. keys as standard function keys only when a specific application is active?
