Hi geekhackers

<3
I'd like to make the F1-F6 keys on my Filco into media keys (my previous keyboard, a MK-50, worked this way: Fn + F1=mute, F2=VolDwn, F3=VolUp, F4=play/pause, F5=previous & F6=next). Now, the Filco doesn't have an Fn key, but ctrl or alt would work just as well, I believe.
Achieving this by running a process is just not acceptable to me (AutoHotkey does this, I believe). Is there a way to do this with registry editing? Can it be done at all?
Thanks in advance, and sorry about the subject -- I'm not at my brightest at 5AM. Cheers!
