Currently hitting a keyboard backlight toggle key (e.g. a fn key) switches they keyboard backlight to 0% from any % other then 0% and to 100% when it was 0% before. The percentage it was befor being switched of is not saved. This would be way more usefull if one could for example set keyboard backlight brightness to 50% and then use the toggle key to switch between 0 and 50% instead of 0 and 100%
