# Tri Layers :id=tri-layers
|
||
|
|
|
||
|
|
This enables support for the OLKB style "Tri Layer" keycodes. These function similar to the `MO` (momentary) function key, but if both the "Lower" and "Upper" keys are pressed, it activates a third "Adjust" layer. To enable this functionality, add this line to your `rules.mk`:
|
||
|
|
|
||
|
|
```make
|
||
|
|
TRI_LAYER_ENABLE = yes
|
||
|
|
```
|
||
|
|
|
||
|
|
Note that the "upper", "lower" and "adjust" names don't have a particular significance, they are just used to identify and clarify the behavior. Layers are processed from highest numeric value to lowest, however the values are not required to be consecutive.
|
||
|
|
|
||
|
|
For a detailed explanation of how the layer stack works, check out [Keymap Overview](keymap.md#keymap-and-layers).

## Keycodes :id=keycodes
|
||
|
|
|
||
|
|
| Keycode | Alias | Description |
|
||
|
|
|----------------------|-----------|---------------------------------------------------------------------------------------------------------|
|
||
|
|
| `QK_TRI_LAYER_LOWER` | `TL_LOWR` | Momentarily enables the "lower" layer. Enables the "adjust" layer if the "upper" layer is also enabled" |
|
||
|
|
| `QK_TRI_LAYER_UPPER` | `TL_UPPR` | Momentarily enables the "upper" layer. Enables the "adjust" layer if the "lower" layer is also enabled" |
|
||
|
|
|
||
|
|
## Configuration
|
||
|
|
|
||
|
|
To change the default values for the layers, you can change these defines, in your `config.h`
|
||
|
|
|
||
|
|
| Config name | Default | Description |
|
||
|
|
|--------------------------|---------|------------------------------------------|
|
||
|
|
| `TRI_LAYER_LOWER_LAYER` | `1` | Sets the default for the "lower" layer. |
|
||
|
|
| `TRI_LAYER_UPPER_LAYER` | `2` | Sets the default for the "upper" layer. |
|
||
|
|
| `TRI_LAYER_ADJUST_LAYER` | `3` | Sets the default for the "adjust" layer. |
|
||
|
|
|
||
|
|
Eg, if you wanted to set the "Adjust" layer to be layer 5, you'd add this to your `config.h`:
|
||
|
|
|
||
|
|
```c
|
||
|
|
#define TRI_LAYER_ADJUST_LAYER 5
|
||
|
|
```
|
||
|
|
|
||
|
|
## Functions
|
||
|
|
|
||
|
|
| Function name | Description |
|
||
|
|
|----------------------------------------------|-------------------------------------------------|
|
||
|
|
| `set_tri_layer_lower_layer(layer)` | Changes the "lower" layer*. |
|
||
|
|
| `set_tri_layer_upper_layer(layer)` | Changes the "upper" layer*. |
|
||
|
|
| `set_tri_layer_adjust_layer(layer)` | Changes the "adjust" layer*. |
|
||
|
|
| `set_tri_layer_layers(lower, upper, adjust)` | Stes the "lower", "upper" and "adjust" layers*. |
|
||
|
|
| `get_tri_layer_lower_layer()` | Gets the current "lower" layer. |
|
||
|
|
| `get_tri_layer_upper_layer()` | Gets the current "upper" layer. |
|
||
|
|
| `get_tri_layer_adjust_layer()` | Gets the current "adjust" layer. |
|
||
|
