Custom Keycodes

Keycodes are defined in the process_record.h file and need to be included in the keymap.c files, so that they can be used there.

A bunch of macros are present and are only included on boards that are not the Ergodox EZ or Orthodox, as they are not needed for those boards.

• KC_MAKE - outputs qmk compile -kb (keyboard) -km (keymap) and enter, to start compiling the currenct keyboard. This uses generated variables to always use the current keyboard and keymap. Will work with any keyboard and any keymap.
  • If you are holding shift, it will use qmk flash instead of qmk compile.
  • If MAKE_BOOTLOADER is defined, it will always use qmk flash instead of qmk compile.
• DEFAULT_LAYER_1 ... DEFAULT_LAYER_4 - This sets layer 0-3 as the default layer, and writes that to eeprom, and plays a chime.
• VRSN, outputs the keyboard, keymap, commit and date info. Eg:
  • handwired/tractyl_manuform/5x6_right/f411/drashna @ 0.15.9-162-g087d08, Built on: 2021-12-19-21:10:26
• KC_DIABLO_CLEAR - clears the diablo tapdance status.
• KC_CCCV - Copy on hold, paste on tap.
• KEYLOCK - This unloads the host driver, and prevents any data from being sent to the host. Hitting it again loads the driver, back.
• REBOOT - Uses watchdog timer on AVR, and NVIC_SystemReset() on ChibiOS to reset the board, without jumping to the bootloader.
• EEP_RST - Overrides the default behavior, disables EEPROM (which will trigger a reset on init), and reboots the keyboard as per REBOOT keycode.
