Is it possible to customising function keys?

[EGT]

I’m using a Bluetooth keyboard with my powerbook and I would like to customise the function keys to what they are on the powerbooks keyboard, well, just the brightness, sound and backlight controls.

Can it be done? If so how, exactly. Any help is appreciated .

Thanks :)

I don't know exactly how you do it but if you open System Prefs, Keyboard and Mouse and the go to Keyboard Shortcuts that should be the place to sort out your problem
