How to remap other buttons on keyboard? Those next to the keys. Exp. "airplane-mode", "mute" etc.

Would it be possible to remap buttons on the keyboard which are not keys? Like "airplane-mode", "mute" etc.

I never found use for those buttons, so would be real nice if after all this time they became usefull shortcuts.
