I bought an Ativa illuminated keyboard made for and sold by Office Depot (Ativa item #:617-593). In order to turn the illumination on or off you are supposed to toggle the Scroll-Lock key. This works fine with one HUGE exception. Pushing the Scroll-Lock key to change the illumination also changes the Scroll-Lock! I am looking for a way to change one but not the other. I realize that most functions of this type are usually handled by an FN key to push in conjunction with the Scroll-Lock. This keyboard has no FN key. I have tried every combination with ALT, CTRL, TAB, etc. keys that I can think of and none work. I've called both Office Depot and Ativa and neither could supply any support for this keyboard. Can anyone help?
