# Keycodes Overview When defining a [keymap](keymap.md) each key needs a valid key definition. This page documents the symbols that correspond to keycodes that are available to you in QMK. This is a reference only. Each group of keys links to the page documenting their functionality in more detail. ## Basic Keycodes :id=basic-keycodes See also: [Basic Keycodes](keycodes_basic.md) |Key |Aliases |Description
