3.3 Macro Key Programming
The keyboard features five driverless programmable macro keys (M1-M5). Refer to the advanced customization software for detailed instructions on recording and assigning macros. The software allows for complex key sequences and functions to be assigned to these dedicated keys.

- Fn + F1-F12: Specific multimedia functions (e.g., Play/Pause, Volume Up/Down, Mute, Previous/Next Track). Refer to the keycap legends for exact functions.
