I would like a layout where the whole keyboard is red except for "W, A, S, D, Arrow Keys and G keys" which i would like white. This is where i don't know how to get it to work, I want to make it so that when the "capslock, Numlock, Scroll lock and the mute key" is enabled it changes the colour to blue just like it does with the windows key lock. Much appreciated Lucas
