Command (Formerly known as Magic)

Command is a way to change your keyboard's behavior without having to flash or unplug it to use Bootmagic. There is a lot of overlap between this functionality and the Bootmagic Keycodes. Whenever possible we encourage you to use that functionality instead of Command.

Enabling Command

By default Command is disabled. You can enable it in your rules.mk file:

COMMAND_ENABLE = yes

Usage

To use Command you hold down the key combination defined by IS_COMMAND. By default that combination is both shift keys. While holding the key combination press the key corresponding to the command you want.

For example, to write the current QMK version to the QMK Toolbox console, you can press Left Shift+Right Shift+V.

Configuration

The following values can be defined in config.h to control the behavior of Command.
