# Keycodes Overview
When defining a [keymap](keymap) 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.

<sup>1. The Linux kernel HID driver recognizes [nearly all keycodes](https://github.com/torvalds/linux/blob/master/drivers/hid/hid-input.c), but the default bindings depend on the DE/WM.</sup><br/>
<sup>2. Treated as F13-F15.</sup><br/>
<sup>3. Must be held for about three seconds, and will display a prompt instead.</sup><br/>
<sup>4. Holding Shift+Option allows for finer control of volume level.</sup><br/>
<sup>5. Skips the entire track in iTunes when tapped, seeks within the current track when held.</sup><br/>
<sup>6. WMP does not recognize the Rewind key, but both alter playback speed in VLC.</sup>
