IMHO pressing "fn" to get "f1" to "f10" makes sense. In my daily routine I much more often change volume or brightness than use the numbered F keys.

Looking at this again

I propose:

	f1-f8 produce F key codes both with and without the fn key
	f9-f12 produce F codes only with fn, and volume/brightness events without fn.

So holding down fn always gets you the F key codes, you can change volume/brightness without modifier, and as a bonus you can use the first eight F keys even without the fn key.

This mapping should work both in Sugar and outside.
