This is a community module adaptation of Keycode String, a utility to convert QMK keycodes to human-readable strings. It's much nicer to read names like "LT(2,KC_D)" than numerical codes like "0x4207."

Add the following to your keymap.json:

{
    "modules": ["getreuer/keycode_string"]
}

Then use get_keycode_string(keycode) like:

dprintf("kc=%s\n", get_keycode_string(keycode));

Many common QMK keycodes are understood out of the box by get_keycode_string(), but not all. Optionally, use KEYCODE_STRING_NAMES_USER in keymap.c to define names for additional keycodes or override how any keycode is formatted.

See the Keycode String documentation for further details.
