Keyboard and F's functions

[xoggyux]

Hi, i got an usb wireless keyboard connected to my MBP, im wondering how could i configure my external keyboard F's keys (F1, F2, ---, F12) to do the default functions of the MBP's keyboard (like rise volume, pause/play, expose, dashboard, backlit, and under-keyboard light.
Thanks

If your external keyboard is not an Apple keyboard, I'm afraid you can't.
