# Combos
The Combo feature is a chording type solution for adding custom actions. It lets you hit multiple keys at once and produce a different effect. For instance, hitting `A` and `B` within the combo term would hit `ESC` instead, or have it perform even more complex tasks.
2018-10-10 19:38:10 +00:00
To enable this feature, you need to add `COMBO_ENABLE = yes` to your `rules.mk`.

Then, in your `keymap.c` file, you'll need to define a sequence of keys, terminated with `COMBO_END`, and a structure to list the combination of keys, and its resulting action.

This will send "Escape" if you hit the A and B keys, and Ctrl+Z when you hit the C and D keys.
## Mod-Tap Support
[Mod-Tap](mod_tap.md) feature is also supported together with combos. You will need to use the full Mod-Tap keycode in the combo definition, e.g.:
2018-10-10 19:38:10 +00:00
```c
const uint16_t PROGMEM test_combo1[] = {LSFT_T(KC_A), LT(1, KC_B), COMBO_END};
```
## Overlapping Combos
It is possible to overlap combos. Before, with the example below both combos would activate when all three keys were pressed. Now only the three key combo will activate.

It is worth noting that `COMBO_ACTION`s are not needed anymore. As of [PR#8591](https://github.com/qmk/qmk_firmware/pull/8591/), it is possible to run your own custom keycodes from combos. Just define the custom keycode, program its functionality in `process_record_user`, and define a combo with `COMBO(<key_array>, <your_custom_keycode>)`. See the first example in [Macros](feature_macros.md).

By default, the timeout for the Combos to be recognized is set to 50ms. This can be changed if accidental combo misfires are happening or if you're having difficulties pressing keys at the same time. For instance, `#define COMBO_TERM 40` would set the timeout period for combos to 40ms.

If you're using long combos, or you have a lot of overlapping combos, you may run into issues with this, as the buffers may not be large enough to accommodate what you're doing. In this case, you can configure the sizes of the buffers used. Be aware, larger combo sizes and larger buffers will increase memory usage!
To configure the amount of keys a combo can be composed of, change the following:
| Keys | Define to be set |
|------|-----------------------------------|
| 6 | `#define EXTRA_SHORT_COMBOS` |
| 8 | QMK Default |
| 16 | `#define EXTRA_LONG_COMBOS` |
| 32 | `#define EXTRA_EXTRA_LONG_COMBOS` |
Defining `EXTRA_SHORT_COMBOS` combines a combo's internal state into just one byte. This can, in some cases, save some memory. If it doesn't, no point using it. If you do, you also have to make sure you don't define combos with more than 6 keys.
Processing combos has two buffers, one for the key presses, another for the combos being activated. Use the following options to configure the sizes of these buffers:
| Define | Default |
|-------------------------------------|------------------------------------------------------|
| `#define COMBO_KEY_BUFFER_LENGTH 8` | 8 (the key amount `(EXTRA_)EXTRA_LONG_COMBOS` gives) |
| `#define COMBO_BUFFER_LENGTH 4` | 4 |

If a combo resolves to a Modifier, the window for processing the combo can be extended independently from normal combos. By default, this is disabled but can be enabled with `#define COMBO_MUST_HOLD_MODS`, and the time window can be configured with `#define COMBO_HOLD_TERM 150` (default: `TAPPING_TERM`). With `COMBO_MUST_HOLD_MODS`, you cannot tap the combo any more which makes the combo less prone to misfires.

### Per Combo Timing, Holding, Tapping and Key Press Order
For each combo, it is possible to configure the time window it has to pressed in, if it needs to be held down, if it needs to be tapped, or if its keys need to be pressed in order.
For example, tap-only combos are useful if any (or all) of the underlying keys are mod-tap or layer-tap keys. When you tap the combo, you get the combo result. When you press the combo and hold it down, the combo doesn't activate. Instead the keys are processed separately as if the combo wasn't even there.

### Generic hook to (dis)allow a combo activation
By defining `COMBO_SHOULD_TRIGGER` and its companying function `bool combo_should_trigger(uint16_t combo_index, combo_t *combo, uint16_t keycode, keyrecord_t *record)` you can block or allow combos to activate on the conditions of your choice.
For example, you could disallow some combos on the base layer and allow them on another. Or disable combos on the home row when a timer is running.
Examples:
```c
bool combo_should_trigger(uint16_t combo_index, combo_t *combo, uint16_t keycode, keyrecord_t *record) {
/* Disable combo `SOME_COMBO` on layer `_LAYER_A` */
switch (combo_index) {
case SOME_COMBO:
if (layer_state_is(_LAYER_A)) {
return false;
}
}
return true;
}

With `COMBO_STRICT_TIMER`, the timer is started only on the first key press.
Inputting combos is now less relaxed; you need to make sure the full chord is pressed within the `COMBO_TERM`.
Misfires are less common but if you type multiple combos fast, there is a
chance that the latter ones might not activate properly.

By defining `COMBO_NO_TIMER`, the timer is disabled completely and combos are activated on the first key release.
This also disables the "must hold" functionalities as they just wouldn't work at all.

By defining `COMBO_PROCESS_KEY_RELEASE` and implementing the function `bool process_combo_key_release(uint16_t combo_index, combo_t *combo, uint8_t key_index, uint16_t keycode)`, you can run your custom code on each key release after a combo was activated. For example you could change the RGB colors, activate haptics, or alter the modifiers.
You can also release a combo early by returning `true` from the function.
Here's an example where a combo resolves to two modifiers, and on key releases the modifiers are unregistered one by one, depending on which key was released.

If you, for example, use multiple base layers for different key layouts, one for QWERTY, and another one for Colemak, you might want your combos to work from the same key positions on all layers. Defining the same combos again for another layout is redundant and takes more memory. The solution is to just check the keycodes from one layer.
With `#define COMBO_ONLY_FROM_LAYER 0` in config.h, the combos' keys are always checked from layer `0`, even if other layers are active.

#### Combo reference layers by layer.
If not using `COMBO_ONLY_FROM_LAYER` it is possible to specify a
combo reference layer for any layer using the `combo_ref_from_layer` hook.
The combo macros automatically create this function from the `COMBO_REF_LAYER()`
entries given.
This function returns the assigned reference layer for the current layer.
if there is no match, it returns the default reference layer if set,
or the current layer otherwise. A default layer can be set with
`DEFAULT_REF_LAYER(_MY_COMBO_REF_LAYER)`
If not set, the default reference layer selection from the automatically generated
`combo-ref-from-layer()` will be the current layer.
The following `combo_ref_from_layer` function
will give a reference layer of _QWERTY for the _DVORAK layer and
will give the _NAV layer as a reference to it's self. All other layers
will have the default for their combo reference layer. If the default
is not set, all other layers will reference themselves.
2024-02-20 00:45:25 +00:00
```c
#define COMBO_REF_DEFAULT _MY_COMBO_LAYER
uint8_t combo_ref_from_layer(uint8_t layer){
switch (get_highest_layer(layer_state)){
case _DVORAK: return _QWERTY;
case _NAV: return _NAV;
default: return _MY_COMBO_LAYER;
}
2024-02-20 00:45:25 +00:00
return layer; // important if default is not in case.
}
```
The equivalent definition using the combo macros is this:
2024-02-20 00:45:25 +00:00
```c
COMBO_REF_LAYER(_DVORAK, _QWERTY)
COMBO_REF_LAYER(_NAV, _NAV)
DEFAULT_REF_LAYER(_MY_COMBO_LAYER).
```
## User callbacks
In addition to the keycodes, there are a few functions that you can use to set the status, or check it:
|Function |Description |
|-----------|--------------------------------------------------------------------|
| `combo_enable()` | Enables the combo feature |
| `combo_disable()` | Disables the combo feature, and clears the combo buffer |
| `combo_toggle()` | Toggles the state of the combo feature |
| `is_combo_enabled()` | Returns the status of the combo feature state (true or false) |

Having 3 places to update when adding new combos or altering old ones does become cumbersome when you have a lot of combos. We can alleviate this with some magic! ... If you consider C macros magic.
First, you need to add `VPATH += keyboards/gboards` to your `rules.mk`. Next, include the file `g/keymap_combo.h` in your `keymap.c`.
!> This functionality uses the same `process_combo_event` function as `COMBO_ACTION` macros do, so you cannot use the function yourself in your keymap. Instead, you have to define the `case`s of the `switch` statement by themselves within `inject.h`, which `g/keymap_combo.h` will then include into the function.
Then, write your combos in `combos.def` file in the following manner:
```c
// Alternate reference layers by layer
// Layer Reference layer
COMBO_REF_LAYER(_DVORAK, _QWERTY) // reference the qwerty layer for dvorak.
COMBO_REF_LAYER(_NAV, _NAV) // explicit reference to self instead of the default.

Possibly can save some space. * Add more examples and clarify things with dict management system. - Simple examples now has a combo that has modifiers included. - The slightly more advanced examples now are actually more advanced instead of just `tap_code16(<modded-keycode>)`. - Added a note that `COMBO_ACTION`s are not needed anymore as you can just use custom keycodes. - Added a note that the `g/keymap_combo.h` macros use the `process_combo_event` function and that it is not usable in one's keymap afterwards. * Update docs/feature_combo.md Co-authored-by: precondition <57645186+precondition@users.noreply.github.com> * Update docs/feature_combo.md Co-authored-by: precondition <57645186+precondition@users.noreply.github.com> * Update docs/feature_combo.md Co-authored-by: precondition <57645186+precondition@users.noreply.github.com> * Update docs/feature_combo.md Co-authored-by: precondition <57645186+precondition@users.noreply.github.com> * Update docs/feature_combo.md Co-authored-by: precondition <57645186+precondition@users.noreply.github.com> * Change "the" combo action example to "email" example. * Update docs/feature_combo.md Co-authored-by: precondition <57645186+precondition@users.noreply.github.com> * Fix sneaky infinite loop with `combo_disable()` No need to call `dump_key_buffer` when disabling combos because the buffer is either being dumped if a combo-key was pressed, or the buffer is empty if a non-combo-key is pressed. * Update docs/feature_combo.md Co-authored-by: precondition <57645186+precondition@users.noreply.github.com> * Update docs/feature_combo.md Co-authored-by: precondition <57645186+precondition@users.noreply.github.com> Co-authored-by: precondition <57645186+precondition@users.noreply.github.com> Co-authored-by: Drashna Jaelre <drashna@live.com>
