Bootmagic

There are three separate but related features that allow you to change the behavior of your keyboard without reflashing. While each of them have similar functionality, it is accessed in different ways depending on how your keyboard is configured.

Bootmagic is a system for configuring your keyboard while it initializes. To trigger a Bootmagic command, hold down the Bootmagic key and one or more command keys.

Bootmagic Keycodes are prefixed with MAGIC_, and allow you to access the Bootmagic functionality after your keyboard has initialized. To use the keycodes, assign them to your keymap as you would any other keycode.

Command, formerly known as Magic, is another feature that allows you to control different aspects of your keyboard. While it shares some functionality with Bootmagic, it also allows you to do things that Bootmagic does not, such as printing version information to the console. For more information, see Command.

On some keyboards Bootmagic is disabled by default. If this is the case, it must be explicitly enabled in your rules.mk with:

BOOTMAGIC_ENABLE = yes

Hotkeys

Hold down the Bootmagic key (Space by default) and the desired hotkey while plugging in your keyboard. For example, holding Space+B should cause it to enter the bootloader.
