The new UI framework introduced by hawhill can easily support arbitrary key combinations. But current UI framework only supports shift and alt combo (you can still implement arbitrary key combinations, but the code will look very ugly). So if you want to use shift+home to exit kpv, you can try change the two lines I mentioned to:

elseif ev.code == KEY_BACK or ev.code == KEY_HOME then
	if Keys.shiftmode == true then
		return nil
	end
end

Or you can wait for the integration of new UI framework.
