  // 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.
