Overview

When defining a keymap each key needs a valid key definition.

This page documents the symbols that correspond to keycodes that are available to you in QMK.

Basic keycodes (`0x00` - `0xFF`)

Basic keycodes in QMK are based on HID Usage Keyboard/Keypad Page(0x07) with following exceptions:

KC_NO = 0 for no action
KC_TRNS = 1 for layer transparency
internal special keycodes in the 0xA5-DF range (tmk heritage).

Quantum keycodes (`0x0100` - `0xFFFF`)

Quantum keycodes allow for easier customisation of your keymap than the basic ones provide, without having to define custom actions.
