# Basic keycodes
Basic keycodes are based on [HID Usage Keyboard/Keypad Page(0x07)](http://www.usb.org/developers/hidpage/Hut1_12v2.pdf) with following exceptions:
* `KC_NO` = 0 for no action
* `KC_TRNS` = 1 for layer transparency
* internal special keycodes in the `0xA5-DF` range (tmk heritage).

# Backlighting
<!-- FIXME: Describe how backlighting works in QMK -->
## Backlight Keycodes
These keycodes control the backlight. Most keyboards use this for single color in-switch lighting.
|Name|Description|
|----|-----------|
|`BL_x`|Set a specific backlight level between 0-9|
|`BL_ON`|An alias for `BL_9`|
|`BL_OFF`|An alias for `BL_0`|
|`BL_DEC`|Turn the backlight level down by 1|
|`BL_INC`|Turn the backlight level up by 1|
|`BL_TOGG`|Toggle the backlight on or off|
|`BL_STEP`|Step through backlight levels, wrapping around to 0 when you reach the top.|

@ -25,7 +25,9 @@ These functions allow you to activate layers in various ways.
* `TO(layer)` - Goes to a layer. This code is special, because it lets you go either up or down the stack -- just goes directly to the layer you want. So while other codes only let you go _up_ the stack (from layer 0 to layer 3, for example), `TO(2)` is going to get you to layer 2, no matter where you activate it from -- even if you're currently on layer 5. This gets activated on keydown (as soon as the key is pressed).
* `TT(layer)` - Layer Tap-Toggle. If you hold the key down, the layer becomes active, and then deactivates when you let go. And if you tap it, the layer simply becomes active (toggles on). It needs 5 taps by default, but you can set it by defining `TAPPING_TOGGLE`, for example, `#define TAPPING_TOGGLE 2` for just two taps.
Care must be taken when switching layers, it's possible to lock yourself in a layer with no way to deactivate that layer (without unplugging your keyboard.) We've created some guidelines to help users avoid the most common problems.

# Overview
When defining a [keymap](keymap.md) each key needs a valid key definition.
When defining a [keymap](keymap.md) 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. Where possible keys link to the page documenting their functionality.
This page documents the symbols that correspond to keycodes that are available to you in QMK.
## Keycode Index
## Basic keycodes (`0x00` - `0xFF`)
[Basic keycodes](basic_keycodes.md) in QMK are based on [HID Usage Keyboard/Keypad Page(0x07)](http://www.usb.org/developers/hidpage/Hut1_12v2.pdf) with following exceptions:
* `KC_NO` = 0 for no action
* `KC_TRNS` = 1 for layer transparency
* internal special keycodes in the `0xA5-DF` range (tmk heritage).
## Quantum keycodes (`0x0100` - `0xFFFF`)
[Quantum keycodes](quantum_keycodes.md) allow for easier customisation of your keymap than the basic ones provide, without having to define custom actions.

# Quantum Keycodes
Quantum keycodes allow for easier customisation of your keymap than the basic ones provide, without having to define custom actions.
All keycodes within quantum are numbers between `0x0000` and `0xFFFF`. Within your `keymap.c` it may look like you have functions and other special cases, but ultimately the C preprocessor will translate those into a single 4 byte integer. QMK has reserved `0x0000` through `0x00FF` for standard keycodes. These are keycodes such as `KC_A`, `KC_1`, and `KC_LCTL`, which are basic keys defined in the USB HID specification.
On this page we have documented keycodes between `0x00FF` and `0xFFFF` which are used to implement advanced quantum features. If you define your own custom keycodes they will be put into this range as well. Keycodes above `0x00FF` may not be used with any of the mod/layer-tap keys listed
On this page we have documented keycodes between `0x00FF` and `0xFFFF` which are used to implement advanced quantum features. If you define your own custom keycodes they will be put into this range as well.

### One Shot Keys
Most modifiers work by being held down while you push another key. You can use `OSM()` to setup a "One Shot" modifier. When you tap a one shot mod it will remain is a pressed state until you press another key.
To specify a your modifier you need to pass the `MOD` form of the key. For example, if you want to setup a One Shot Control you would use `OSM(MOD_LCTL)`.

|`OSM(mod)`|use mod for one keypress|
|`OSL(layer)`|switch to layer for one keypress|

|`DF(layer)`|sets the base (default) layer|
|`TG(layer)`|toggle layer on/off|
|`TT(layer)`|tap toggle? idk FIXME|
|`OSL(layer)`|switch to layer for one keycode|
## Unicode
These keycodes can be used in conjuction with the [Unicode](unicode_and_additional_language_support.md) support.
|`UNICODE(n)`/`UC(n)`|if `UNICODE_ENABLE`, this will send characters up to `0x7FFF`|
|`X(n)`|if `UNICODEMAP_ENABLE`, also sends unicode via a different method|
# `SAFE_RANGE`, or safely defining custom keycodes
Sometimes you want to define your own custom keycodes to make your keymap easier to read. QMK provides `SAFE_RANGE` to help you do that. `SAFE_RANGE` is the first available keycode in the `0x0000`-`0xFFFF` range and you can use it when creating your own custom keycode enum:
```
enum my_keycodes {
FOO = SAFE_RANGE,
BAR
};
```
You can then use `process_record_user()` to do something with your keycode:
```
bool process_record_user(uint16_t keycode, keyrecord_t *record) {
switch (keycode) {
case FOO:
// Do something here
break;
case BAR:
// Do something here
break;
}
}
```
