# Bootmagic and Magic Keycodes
# Bootmagic
There are 3 separate but related features that allow you to change the behavior of your keyboard without reflashing. While each of them have similar functionality you access that functionality in different ways depending on how your keyboard is configured.
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 you hold down the bootmagic key (`KC_SPACE` on most keyboards) and one or more command keys.
**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 allow you to access the Bootmagic functionality after your keyboard has initialized. To use Bootmagic Keycodes you assign keycodes starting with `MAGIC_`, much in the same way you define any other key.
**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 is a feature that allows you to control different aspects of your keyboard. Command used to be called Magic. Command is typically accessed by holding Left and Right Shift at the same time, although that can be customized. While it shares some functionality with Bootmagic it also allows you to access functionality that Bootmagic does not. For more information see the [Command](feature_command.md) documentation page.
**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](feature_command.md).
## Enabling Bootmagic
On some keyboards Bootmagic is disabled by default. If this is the case, it must be explicitly enabled in your `rules.mk` with:
Bootmagic is disabled by default. To use Bootmagic you need to enable it in your `rules.mk` file:
```make
BOOTMAGIC_ENABLE = yes
```
BOOTMAGIC_ENABLE = yes
## Hotkeys
## Bootmagic Hotkeys and Keycodes
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.
This table describes the default Hotkeys for Bootmagic and the Keycodes for Magic. These may be overriden at the Keyboard or Keymap level. Some functionality is not available in both methods.
|Hotkey |Description |
|------------------|---------------------------------------------|
|Escape |Ignore Bootmagic configuration in EEPROM |
|`B` |Enter the bootloader |
|`D` |Toggle debugging over serial |
|`X` |Toggle key matrix debugging |
|`K` |Toggle keyboard debugging |
|`M` |Toggle mouse debugging |
|Backspace |Clear the EEPROM |
|Caps Lock |Toggle treating Caps Lock as Left Control |
|Left Control |Toggle swapping Caps Lock and Left Control |
|Left Alt |Toggle swapping Left Alt and Left GUI |
|Right Alt |Toggle swapping Right Alt and Right GUI |
|Left GUI |Toggle the GUI keys (useful when gaming) |
|<code>&#96;</code>|Toggle swapping <code>&#96;</code> and Escape|
|`\` |Toggle swapping `\` and Backspace |
|`N` |Toggle N-Key Rollover (NKRO) |
|`0` |Make layer 0 the default layer |
|`1` |Make layer 1 the default layer |
|`2` |Make layer 2 the default layer |
|`3` |Make layer 3 the default layer |
|`4` |Make layer 4 the default layer |
|`5` |Make layer 5 the default layer |
|`6` |Make layer 6 the default layer |
|`7` |Make layer 7 the default layer |
To use the Hotkey hold down `BOOTMAGIC_KEY_SALT` (`KC_SPACE` by default) and the Hotkey while plugging in your keyboard. To use the Keycode assign that keycode to a layer. For example, if you hold down Space+B while plugging in most keyboards, you will enter bootloader mode.

## Bootmagic Configuration
## Configuration
When setting up your keyboard and/or keymap there are a number of `#define`s that control the behavior of Bootmagic. To use these put them in your `config.h`, either at the keyboard or keymap level.
If you would like to change the hotkey assignments for Bootmagic, `#define` these in your `config.h` at either the keyboard or keymap level.

# Command (Formerly known as Magic)
# Command
Command is a way to change your keyboard's behavior without having to flash or unplug it to use [Bootmagic](feature_bootmagic.md). There is a lot of overlap between this functionality and the [Bootmagic Keycodes](feature_bootmagic.md). Whenever possible we encourage you to use that functionality instead of Command.
Command, formerly known as Magic, is a way to change your keyboard's behavior without having to flash or unplug it to use [Bootmagic](feature_bootmagic.md). There is a lot of overlap between this functionality and the [Bootmagic Keycodes](feature_bootmagic.md#keycodes). Wherever possible we encourage you to use that feature instead of Command.
## Enabling Command
On some keyboards Command is disabled by default. If this is the case, it must be explicitly enabled in your `rules.mk`:
By default Command is disabled. You can enable it in your `rules.mk` file:
COMMAND_ENABLE = yes
```make
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`.
To use Command, hold down the key combination defined by the `IS_COMMAND()` macro. By default this is Left Shift+Right Shift. Then, press the key corresponding to the command you want. For example, to output the current QMK version to the QMK Toolbox console, press Left Shift+Right Shift+`V`.
## Configuration
The following values can be defined in `config.h` to control the behavior of Command.
If you would like to change the key assignments for Command, `#define` these in your `config.h` at either the keyboard or keymap level. All keycode assignments here must omit the `KC_` prefix.
