Great keyboard. Had to do some searching to find out how to manipulate the LED light. Here is what I found. Highly recommend this product.So there are two different things: the "side LED" -- that's the rim around the keyboard that lights up in various ways and the keys themselves. And both of these can have their color manipulated in various ways.All the changes are controlled by function keys + something else.Side LED:Fn + PrtSc = you get a full, rainbow-color border around the keyboard. (IF it's in a mode where that applies, given the Fn + PgDn status)Fn + Pause = you get one specific color border around the keyboard (red, green, blue, white, light blue, light magenta, dark magenta, orange)... might or might not be changing somehow depending on Fn + PgDn statusFn + PgDn = switches modes for the side LED-the whole LED is a single color that cycles... e.g. blue to green to yellow, etc.-rainbow color that moves counter-clockwise-rainbow color that moves in both directions-stable rainbow colorFn + ,< = decreases speed of the light changes for the side LEDFn + .> = increases speed of the light changes for the side LEDFn + -_ = decreases brightness of the side LED, all the way down to "off"Fn + =+ = increases brightness of the side LEDKeys:The modes under "Ins" "Del" and "Home" appear to be choices... each of them has a menu of options, and if you pick an option in one category, then the other categories are deactivated.Fn + Ins = cycles between several modes for how the keys light up.1. Pressing a key sends rainbow light from that key through the whole keyboard.2. Light goes outward from the key pressed only in that row.3. Light moves in two split columns on either away from the key towards the rest4. A key lights only itself up, and the light lasts briefly.5. All the keys are lit up continuously with stable light.Fn + Home = "breathing mode," so the whole keyboard is lit up with a color that changes continuously, as if the keyboard is 'breathing'Fn + PgUp = changes the color of the key presses to a single color instead of mixed colors... that single color can be changed by pressing this repeatedly.Fn + Del = Several more light modes for the keys:-All lit up with the same color. This color can be changed by using Fn + Pgup-Random keys all over the keyboard being lit up. Default is mixed colors, but Fn + PgUp can change this to a single color-A pulsing rainbow light under all the keys-A pulsing single light under all the keys-A rainbow light under rthe keys that changes in a wave-like fashion under the keys-A different kind of wave, this oen going more left to right...-Yet another kind of wave, kind of bouncing-Another kind of wave, going in diagonals-Another kind of wave, going across rowsFn + End = turns all the lights on the keys offFn + up arrow key = increases brightness of key lightFn + down arrow key = decreases brightness of key lightFn + left arrow key = decreases speed of key light changesFn + right arrow key = decreases speed of key light changes
