What I tried: entering the defined QMK KC_LPAD or KC_MCTL as documented in https://docs.qmk.fm/keycodes
What I expected: to be able to hit Commit to bind a key to these documented codes
What happened: No variation of these codes as documented by the QMK website worked
Codes:
KC_MISSION_CONTROL KC_MCTL Open Mission Control
KC_LAUNCHPAD KC_LPAD Open Launchpad
