Long-life LED backlighting can be set to two different brightness levels-or turned off completely. So you can play in the dark and still see the keys. Six programmable keys with three mode states each provide up to 18 possible macro combinations per game. You can perform either single keystrokes or intricate macros with multiple keystrokes, mouse events, user-defined delays, and repeating. You can even record new macros on-the-fly.
