Home and End buttons with Fn key not working

[Yaco]

Thanks for this great patch.

There is a still a very important function of the original Thinkpad keyboard that is not working in the external one. When you press Fn + Left it should trigger the Home function; with Fn + Right it should trigger the End function.

This is very important for users focused in rapid text editing. Could you add this fix to your patch?

Thanks!
