# 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.

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.
2. Treated as F13-F15.
3. Must be held for about three seconds, and will display a prompt instead.
4. Holding Shift+Option allows for finer control of volume level.
5. Skips the entire track in iTunes when tapped, seeks within the current track when held.
6. WMP does not recognize the Rewind key, but both alter playback speed in VLC.
