Keycodes are defined in the drashna.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.
Included is a custom macro for compiling my keyboards. This includes the bootloader target (:teensy, :avrdude, or :dfu), and keeps RGBLIGHT, AUDIO and/or FAUXCLICKY enabled, if it previously was (regardless of the rules file).
This also includes a modified RESET keycode as well, that sets the underglow to red.
