Here's what I've been able to figure out so far (I use this on a Mac):
FN + M (hold 2-3 seconds) = Mac Mode/Windows Mode Toggle (CapsLock flashes when toggled)
FN + Top Row key (1 through =) = F1 through F12
FN + Delete = Sound mute/unmute toggle
FN + PgUp = Increase sound volume
FN + PgDn = Decrease sound volume
FN + Backslash = Cycle through lighting effects
FN + Esc = Solid color backlight
FN + Enter = Change color of backlight
FN + Down Arrow = Decrease lighting brightness (Turn all the way down for OFF)
FN + Up Arrow = Increase lighting brightness
FN + Left Arrow = Increase speed of some lighting effects
FN + Right Arror = Decrease speed of some lighting effects
FN + Spacebar = Freeze some lighting effects (Lights stay on, animation stops)
FN + CapsLock = Change color of CapsLock indicator
(TIP: Turn CapsLock ON first to see what color you are selecting.)
LED under `/~ (Backtick/Tilde) = Battery indicator. Pulsates green while charging, Pulsates red when battery is low.
Reset the keyboard (Hold 4 corner keys: Esc + Tilde + Control + Right Arrow)
Hold FN + Backspace for 2 seconds until Backspace flashes = Enter record mode to save a profile. While in record mode you can cycle through the color of each keys backlight until you get the color you want. FN + Backspace = Exit record mode and save profile. FN + Backspace = Recall saved profile.
NOTE: This will let you edit and save 1 profile. There's a way to edit and save 2 profiles using the FN+PgUp and FN+PgDn keys. Haven't figured that out just yet!
FN + Tab = Is supposed to set light sleep time, but I can't get it to work! Caps light flashes once for sleep after 2 minutes. Caps light flashes twice for sleep after 30 minutes. Caps light flashes 3 times for no sleep.
The yellow accent keys look nice... UNTIL you turn on any lighting effects. The light shines through the yellow plastic in spots.
Bluetooth:
FN + R = Toggle Bluetooth on/off (Q key backlight flashes while waiting to be paired)
Mac displays a code to type on the keyboard to pair. (Q backlight goes out when paired)
I've not had much luck with Bluetooth yet. Disconnects as soon as I unplug USB. (Edit: DUH! Turn switch on bottom of keyboard ON before unplugging!) (Another edit: Switch is not the entire problem. Still having problems getting Bluetooth to connect and stay connected!)
(Edit again: Updated command list with additional functions from translated manual)
