Type with ease — even after dark. Light the entire to see every key, or choose between five lighting patterns. Set the mood with “breathing” or “serpent” patterns. Light up each key you hit with “reactive lighting,” or choose “random” for a twinkling effect. There’s a lighting pattern for you — no matter how you work (or play). Use FN+F12 to switch between illumination patterns and FN+F1/F2 to decrease, and increase the brightness.
