FN + ~ locks the keyboard FN + Left Arrow Key cycles through the LED patterns (Fully lit, key press ripple, marquee/snake from left to right top row to bottom, and illuminate key on press. FN + Right arrow key toggles breathing FN + Up/Down arrow key changes LED brightness
FN + F1 is My Computer FN + F2 is default browser FN + F3 is calculator FN + F4 is default media player FN + F5-F11 are media/volume keys FN + F12 is winlock (enable/disable toggle for win key)
Not entirely sure about these FN + INS turns on 6 key rollover FN + HM turns on 24 key rollover
No freaking clue FN + DEL FN + END FN + PD
I did try Google'ing for documentation, video or text, but my Google-Fu betrays me.
Any thoughts to if the board has programmable macros too? That would make sense for the FN + DEL, END and PD keys, delays for macros.
