    // The FN key by default maps to a momentary toggle to layer 1 to provide access to the RESET key (to put the board into bootloader mode). Without
    // this mapping, you have to open the case to hit the button on the bottom of the PCB (near the USB cable attachment) while plugging in the USB
    // cable to get the board into bootloader mode - definitely not fun when you're working on your QMK builds. Remove this and put it back to KC_RGUI
    // if that's your preference.
    //
    // To put the keyboard in bootloader mode, use FN+backslash. If you accidentally put it into bootloader, you can just unplug the USB cable and
    // it'll be back to normal when you plug it back in.
    //
    // This keyboard defaults to 6KRO instead of NKRO for compatibility reasons (some KVMs and BIOSes are incompatible with NKRO).
    // Since this is, among other things, a "gaming" keyboard, a key combination to enable NKRO on the fly is provided for convenience.
    // Press Fn+N to toggle between 6KRO and NKRO. This setting is persisted to the EEPROM and thus persists between restarts.
    //
    // RGB and function keys are inspired by the Keychron Q1 layouts instead of using the default keys.
    //
    // KC_PAUS/KC_BRMU and KC_SCRL/KC_BRMD are aliases for the same keys, but their names reflect better the function in each layout.
