You have to make backlit keys always on as an option. I dont want the backlit to turn off, it is annoying. I need the backlit of the keys to be alway on when I write, I toggle between reading on screen and typing, when the backlit goes off I have to wait for the light to turn on again as I go back and forth between screen and keys, in a dark room. Frustrating and annoying. PLease make always on option.
