# Quantum Keycodes
|
|
|
|
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
|
|

### 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)`.
|
|
|
|
|Name|Description|
|
|
|----|-----------|
|
|
|`OSM(mod)`|use mod for one keypress|
|
|
|`OSL(layer)`|switch to layer for one keypress|
|
|
|
|
### Mod-tap keys
|
|
|
|
These keycodes will press the mod(s) when held, and the key when tapped. They only work with [basic keycodes](basic_keycodes.md).
|
|
|
|
|Name|Description|
|
|
|----|-----------|
|
|
|`CTL_T(kc)`/`LCTL_T(kc)`|`LCTL` when held, `kc` when tapped|
|
|
|`RCTL_T(kc)`|`RCTL` when held, `kc` when tapped|
|
|
|`SFT_T(kc)`/`LSFT_T(kc)`|`LSFT` when held, `kc` when tapped|
|
|
|`RSFT_T(kc)`|`RSFT` when held, `kc` when tapped|
|
|
|`ALT_T(kc)`/`LALT_T(kc)`|`LALT` when held, `kc` when tapped|
|
|
|`RALT_T(kc)`/`ALGR_T(kc)`|`RALT` when held, `kc` when tapped|
|
|
|`GUI_T(kc)`/`LGUI_T(kc)`|`LGUI` when held, `kc` when tapped|

|
|
|`LCAG_T(kc)`|`LCTL` + `LALT` + `LGUI` when held, `kc` when tapped|
|
|
|`RCAG_T(kc)`|`RCTL` + `RALT` + `RGUI` when held, `kc` when tapped|
|
|
|`ALL_T(kc)`|`LCTL` + `LSFT` + `LALT` + `LGUI` when held, `kc` when tapped [more info](http://brettterpstra.com/2012/12/08/a-useful-caps-lock-key/)|
|
|
|`SCMD_T(kc)`/`SWIN_T(kc)`|`LGUI` + `LSFT` when held, `kc` when tapped|
|
|
|`LCA_T(kc)`|`LCTL` + `LALT` when held, `kc` when tapped|
|
|
|
|
## US ANSI Shifted symbols
|
|
|
|
These keycodes correspond to characters that are "shifted" on a standard US ANSI keyboards. They do not have dedicated keycodes but are instead typed by holding down shift and then sending a keycode.
|
|
|
|
It's important to remember that all of these keycodes send a left shift - this may cause unintended actions if unaccounted for. The short code is preferred in most situations.
|
|
|
|
|Short Name|Long Name|Description|
|
|
|----------|---------|-----------|
|
|
|`KC_TILD`|`KC_TILDE`|tilde `~`|
|
|
|`KC_EXLM`|`KC_EXCLAIM`|exclamation mark `!`|
|
|
|`KC_AT`||at sign `@`|
|
|
|`KC_HASH`||hash sign `#`|
|
|
|`KC_DLR`|`KC_DOLLAR`|dollar sign `$`|
|
|
|`KC_PERC`|`KC_PERCENT`|percent sign `%`|
|
|
|`KC_CIRC`|`KC_CIRCUMFLEX`|circumflex `^`|
|
|
|`KC_AMPR`|`KC_AMPERSAND`|ampersand `&`|
|
|
|`KC_ASTR`|`KC_ASTERISK`|asterisk `*`|
|
|
|`KC_LPRN`|`KC_LEFT_PAREN`|left parenthesis `(`|
|
|
|`KC_RPRN`|`KC_RIGHT_PAREN`|right parenthesis `)`|
|
|
|`KC_UNDS`|`KC_UNDERSCORE`|underscore `_`|
|
|
|`KC_PLUS`||plus sign `+`|
|
|
|`KC_LCBR`|`KC_LEFT_CURLY_BRACE`|left curly brace `{`|

|
## Layer Changes
|
|
|
|
These are keycodes that can be used to change the current layer.
|
|
|
|
|Name|Description|
|
|
|----|-----------|
|
|
|`LT(layer, kc)`|turn on layer (0-15) when held, kc ([basic keycodes](basic_keycodes.md)) when tapped|
|
|
|`TO(layer)`|turn on layer when depressed|
|
|
|`MO(layer)`|momentarily turn on layer when depressed (requires `KC_TRNS` on destination layer)|
|
|
|`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;
|
|
}
|
|
}
|
|
```
|
