 # Backlighting
 
-<!-- FIXME: Describe how backlighting works in QMK -->
+Many keyboards support backlit keys by way of individual LEDs placed through or underneath the keyswitches. QMK is able to control the brightness of these LEDs by switching them on and off rapidly in a certain ratio, a technique known as *Pulse Width Modulation*, or PWM. By altering the duty cycle of the PWM signal, it creates the illusion of dimming.
 
-## Backlight Keycodes
+The MCU can only supply so much current to its GPIO pins. Instead of powering the backlight directly from the MCU, the backlight pin is connected to a transistor or MOSFET that switches the power to the LEDs.
 
-These keycodes control the backlight. Most keyboards use this for single color in-switch lighting.
+## Usage
+
+Most keyboards have backlighting enabled by default if they support it, but if it is not working for you, check that your `rules.mk` includes the following:
+
+```make
+BACKLIGHT_ENABLE = yes
+```
+
+You should then be able to use the keycodes below to change the backlight level.

-Note that for backlight breathing, you need to have `#define BACKLIGHT_BREATHING` in your config.h.
+## Caveats
 
-## Configuration Options in `config.h`
+This feature is distinct from both the [RGB underglow](feature_rgblight.md) and [RGB matrix](feature_rgb_matrix.md) features as it usually allows for only a single colour per switch, though you can obviously use multiple different coloured LEDs on a keyboard.
 
-* `BACKLIGHT_PIN B7` defines the pin that controlls the LEDs. Unless you design your own keyboard, you don't need to set this.
-* `BACKLIGHT_LEVELS 3` defines the number of brightness levels (maximum 15 excluding off).
-* `BACKLIGHT_BREATHING` if defined, enables backlight breathing. Note that this is only available if `BACKLIGHT_PIN` is B5, B6 or B7.
-* `BREATHING_PERIOD 6` defines the length of one backlight "breath" in seconds.
+Hardware PWM is only supported on certain pins of the MCU, so if the backlighting is not connected to one of them, a software implementation will be used, and backlight breathing will not be available. Currently the supported pins are `B5`, `B6`, `B7`, and `C6`.
 
-## Notes on Implementation
+## Configuration
 
-To change the brightness when using pins B5, B6 or B7, the PWM (Pulse Width Modulation) functionality of the on-chip timer is used.
-The timer is a counter that counts up to a certain TOP value (`0xFFFF` set in ICR1) before resetting to 0.
-We also set an OCR1x register.
-When the counter reaches the value stored in that register, the PWM pin drops to low.
-The PWM pin is pulled high again when the counter resets to 0.
-Therefore, OCR1x basically sets the duty cycle of the LEDs and as such the brightness where `0` is the darkest and `0xFFFF` the brightest setting.
+To change the behaviour of the backlighting, `#define` these in your `config.h`:
 
-To enable the breathing effect, we register an interrupt handler to be called whenever the counter resets (with `ISR(TIMER1_OVF_vect)`).
-In this handler, which gets called roughly 244 times per second, we compute the desired brightness using a precomputed brightness curve.
-To disable breathing, we can just disable the respective interrupt vector and reset the brightness to the desired level.

+
+## Hardware PWM Implementation
+
+When using the supported pins for backlighting, QMK will use a hardware timer configured to output a PWM signal. This timer will count up to `ICRx` (by default `0xFFFF`) before resetting to 0.
+The desired brightness is calculated and stored in the `OCRxx` register. When the counter reaches this value, the backlight pin will go low, and is pulled high again when the counter resets.
+In this way `OCRxx` essentially controls the duty cycle of the LEDs, and thus the brightness, where `0x0000` is completely off and `0xFFFF` is completely on.
+
+The breathing effect is achieved by registering an interrupt handler for `TIMER1_OVF_vect` that is called whenever the counter resets, roughly 244 times per second.
+In this handler, the value of an incrementing counter is mapped onto a precomputed brightness curve. To turn off breathing, the interrupt handler is simply disabled, and the brightness reset to the level stored in EEPROM.

+# 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.

 # Grave Escape
 
-Grave Escape is a feature that allows you to share the grave key (<code>&#96;</code> and `~`) on the same key as Escape. When `KC_GESC` is used it will act as `KC_ESC`, unless Shift or GUI is pressed, in which case it will act as `KC_GRAVE`.
+If you're using a 60% keyboard, or any other layout with no F-row, you will have noticed that there is no dedicated Escape key. Grave Escape is a feature that allows you to share the grave key (<code>&#96;</code> and `~`) with Escape.
 
+## Usage
+
+Replace the `KC_GRAVE` key in your keymap (usually to the left of the `1` key) with `KC_GESC`. When pressed it will behave like `KC_ESC`, but with Shift or GUI held it will send `KC_GRAVE`.
+

 |Key      |Aliases    |Description                                                       |

-## Key Lock: Holding Down Keys for You
+# Key Lock
 
-Sometimes, you need to hold down a specific key for a long period of time. Whether this is while typing in ALL CAPS, or playing a video game that hasn't implemented auto-run, Key Lock is here to help. Key Lock adds a new keycode, `KC_LOCK`, that will hold down the next key you hit for you. The key is released when you hit it again. Here's an example: let's say you need to type in all caps for a few sentences. You hit KC_LOCK, and then shift. Now, shift will be considered held until you hit it again. You can think of key lock as caps lock, but supercharged.
+Sometimes you may find yourself needing to hold down a specific key for a long period of time. Key Lock holds down the next key you press for you. Press it again, and it will be released.
 
-Here's how to use it:
+Let's say you need to type in ALL CAPS for a few sentences. Hit `KC_LOCK`, and then Shift. Now, Shift will be considered held until you tap it again. You can think of Key Lock as Caps Lock, but supercharged.
 
-1. Pick a key on your keyboard. This will be the key lock key. Assign it the keycode `KC_LOCK`. This will be a single-action key: you won't be able to use it for anything else.
-2. Enable key lock by including `KEY_LOCK_ENABLE = yes` in your Makefile.
-3. That's it!
+## Usage
 
-Important: switching layers does not cancel the key lock. Additionally, key lock is only able to hold standard action keys and One Shot modifier keys (for example, if you have your shift defined as `OSM(KC_LSFT)`; see [One Shot Keys](quantum_keycodes.md#one-shot-keys)). This does not include any of the QMK special functions (except One Shot modifiers), or shifted versions of keys such as KC_LPRN. If it's in the [Basic Keycodes](keycodes_basic.md) list, it can be held. If it's not, then it can't be.
+First, enable Key Lock by setting `KEY_LOCK_ENABLE = yes` in your `rules.mk`. Then pick a key in your keymap and assign it the keycode `KC_LOCK`.
+
+## Keycodes
+
+|Keycode  |Description                                                   |

-## Space Cadet Shift: The Future, Built In
-
-Steve Losh [described](http://stevelosh.com/blog/2012/10/a-modern-space-cadet/) the Space Cadet Shift quite well. Essentially, you hit the left Shift on its own, and you get an opening parenthesis; hit the right Shift on its own, and you get the closing one. When hit with other keys, the Shift key keeps working as it always does. Yes, it's as cool as it sounds.
-
-To use it, use `KC_LSPO` (Left Shift, Parenthesis Open) for your left Shift on your keymap, and `KC_RSPC` (Right Shift, Parenthesis Close) for your right Shift.
-
-It's defaulted to work on US keyboards, but if your layout uses different keys for parenthesis, you can define those in your `config.h` like this:
-
-    #define LSPO_KEY KC_9
-    #define RSPC_KEY KC_0
-
-You can also choose between different rollover behaviors of the shift keys by defining:
-
-    #define DISABLE_SPACE_CADET_ROLLOVER
-
-in your `config.h`. Disabling rollover allows you to use the opposite shift key to cancel the space cadet state in the event of an erroneous press instead of emitting a pair of parentheses when the keys are released.
-
-The only other thing you're going to want to do is create a `Makefile` in your keymap directory and set the following:
-
-```
-COMMAND_ENABLE   = no  # Commands for debug and configuration
-```
-
-This is just to keep the keyboard from going into command mode when you hold both Shift keys at the same time.

+# Space Cadet Shift: The Future, Built In
+
+Steve Losh described the [Space Cadet Shift](http://stevelosh.com/blog/2012/10/a-modern-space-cadet/) quite well. Essentially, when you tap Left Shift on its own, you get an opening parenthesis; tap Right Shift on its own and you get the closing one. When held, the Shift keys function as normal. Yes, it's as cool as it sounds.
+
+## Usage
+
+Replace the Left Shift key in your keymap with `KC_LSPO` (Left Shift, Parenthesis Open), and Right Shift with `KC_RSPC` (Right Shift, Parenthesis Close).
+
+## Keycodes
+
+|Keycode  |Description                           |
+|---------|--------------------------------------|
+|`KC_LSPO`|Left Shift when held, `(` when tapped |
+|`KC_RSPC`|Right Shift when held, `)` when tapped|
+
+## Caveats
+
+Space Cadet's functionality can conflict with the default Command functionality when both Shift keys are held at the same time. Make sure that Command is disabled in your `rules.mk` with:
+
+```make
+COMMAND_ENABLE = no
+```
+
+## Configuration
+
+By default Space Cadet assumes a US ANSI layout, but if your layout uses different keys for parentheses, you can redefine them in your `config.h`.
+You can also disable the rollover, allowing you to use the opposite Shift key to cancel the Space Cadet state in the event of an erroneous press, instead of emitting a pair of parentheses when the keys are released.

+# Space Cadet Shift Enter
+
+Based on the [Space Cadet Shift](feature_space_cadet_shift.md) feature. Tap the Shift key on its own, and it behaves like Enter. When held, the Shift functions as normal.
+
+## Usage
+
+Replace any Shift key in your keymap with `KC_SFTENT` (Shift, Enter), and you're done.
+
+## Keycodes
+
+|Keycode    |Description                             |
+|-----------|----------------------------------------|
+|`KC_SFTENT`|Right Shift when held, Enter when tapped|
+
+## Caveats
+
+As with Space Cadet Shift, this feature may conflict with Command, so it should be disabled in your `rules.mk` with:
+
+```make
+COMMAND_ENABLE = no
+```
+
+This feature also uses the same timers as Space Cadet Shift, so using them in tandem may produce strange results.
+
+## Configuration
+
+By default Space Cadet assumes a US ANSI layout, but if you'd like to use a different key for Enter, you can redefine it in your `config.h`:
+
+|Define      |Default |Description                                     |

-## Space Cadet Shift Enter: The future, built in
-
-Based on the Space Cadet Shift by Steve Losh [described](http://stevelosh.com/blog/2012/10/a-modern-space-cadet/) 
-Essentially, you hit the Shift on its own, and it acts as the enter key. When hit with other keys, the Shift key keeps working as it always does. Yes, it's as cool as it sounds. This solution works better than using a macro since the timers defined in quantum allow us to tell when another key is pressed, rather than just having a janky timer than results in accidental endlines. 
-
-To use it, use `KC_SFTENT` (Shift, Enter) for any Shift on your keymap.
-
-It's defaulted to work on US keyboards, but if you'd like to use a different key for Enter, you can define those in your `config.h` like this:
-
-    #define SFTENT_KEY KC_ENT
-
-
-The only other thing you're going to want to do is create a `rules.mk` in your keymap directory and set the following:
-
-```
-COMMAND_ENABLE   = no  # Commands for debug and configuration
-```
-
-This is just to keep the keyboard from going into command mode when you hold both Shift keys at the same time.
-
-
-
-
-
-PLEASE NOTE: this feature uses the same timers as the Space Cadet Shift feature, so using them in tandem may produce unwanted results.

This allows you to have features in your userspace `rules.mk` that depend on individual QMK features that may or may not be available on a specific keyboard. For example, if you have RGB control features shared between all your keyboards that support RGB lighting, you can `define RGB_ENABLE` in your keymap `rules.mk` and then check for the variable in your userspace `rules.mk` like this:
+```make
+ifdef RGB_ENABLE

+```make

+This will ensure that you can explicitly turn off features for an individual keymap.

+# The default ANSI keymap for DC01 Left
+
+The keymap looks like a full layout keymap.
+
+This is because the left part of the keyboard acts as the masterm coordinating all four part.
+
+When using the keyboard to connect the other three parts, this keymap overwrites the individual keymaps of the single modules.
+
+When using a module individually, the keymap of that module will take effect.
