Usually, this is `INPUT_EV_KEY` for key/button events. The default value if omitted is `INPUT_EV_KEY`. +- `codes` - The specific codes of the given type to capture, e.g. [button event codes](https://github.com/zmkfirmware/zephyr/blob/v3.5.0%2Bzmk-fixes/include/zephyr/dt-bindings/input/input-event-codes.h#L180). This list must be the same length as the `bindings` property. +- `bindings` - The bindings to trigger when an event with the corresponding code is processed. diff --git a/docs/docs/keymaps/input-processors/index.md b/docs/docs/keymaps/input-processors/index.md index 489003b8303..c854b5369e7 100644 --- a/docs/docs/keymaps/input-processors/index.md +++ b/docs/docs/keymaps/input-processors/index.md @@ -25,25 +25,27 @@ A set of predefined input processors is available by adding the following at the Once included, you can use the following: -| Binding | Processor | Description | -| -------------------------- | ----------------------------------------------------------- | ------------------------------------------------------------------- | -| `&zip_xy_scaler` | [XY Scaler](scaler.md#pre-defined-instances) | Scale a the X/Y input events using a multiplier and divisor | -| `&zip_x_scaler` | [X Scaler](scaler.md#pre-defined-instances) | Scale a the X input events using a multiplier and divisor | -| `&zip_y_scaler` | [Y Scaler](scaler.md#pre-defined-instances) | Scale a the Y input events using a multiplier and divisor | -| `&zip_xy_transform` | [XY Transform](transformer.md#pre-defined-instances) | Transform X/Y values, e.g. inverting or swapping | -| `&zip_scroll_transform` | [Scroll Transform](transformer.md#pre-defined-instances) | Transform wheel/horizontal wheel values, e.g. inverting or swapping | -| `&zip_xy_to_scroll_mapper` | [XY To Scroll Mapper](code-mapper.md#pre-defined-instances) | Map X/Y values to scroll wheel/horizontal wheel events | -| `&zip_xy_swap_mapper` | [XY Swap Mapper](code-mapper.md#pre-defined-instances) | Swap X/Y values | -| `&zip_temp_layer` | [Temporary Layer](temp-layer.md#pre-defined-instances) | Temporarily enable a layer during pointer use | +| Binding | Processor | Description | +| -------------------------- | ------------------------------------------------------------ | ------------------------------------------------------------------- | +| `&zip_xy_scaler` | [XY Scaler](scaler.md#pre-defined-instances) | Scale a the X/Y input events using a multiplier and divisor | +| `&zip_x_scaler` | [X Scaler](scaler.md#pre-defined-instances) | Scale a the X input events using a multiplier and divisor | +| `&zip_y_scaler` | [Y Scaler](scaler.md#pre-defined-instances) | Scale a the Y input events using a multiplier and divisor | +| `&zip_xy_transform` | [XY Transform](transformer.md#pre-defined-instances) | Transform X/Y values, e.g. inverting or swapping | +| `&zip_scroll_transform` | [Scroll Transform](transformer.md#pre-defined-instances) | Transform wheel/horizontal wheel values, e.g. inverting or swapping | +| `&zip_xy_to_scroll_mapper` | [XY To Scroll Mapper](code-mapper.md#pre-defined-instances) | Map X/Y values to scroll wheel/horizontal wheel events | +| `&zip_xy_swap_mapper` | [XY Swap Mapper](code-mapper.md#pre-defined-instances) | Swap X/Y values | +| `&zip_temp_layer` | [Temporary Layer](temp-layer.md#pre-defined-instances) | Temporarily enable a layer during pointer use | +| `&zip_button_behaviors` | [Mouse Button Behaviors](behaviors.md#pre-defined-instances) | Trigger behaviors when certain mouse buttons are pressed | ### User-Defined Processors Several of the input processors that have predefined instances, e.g. `&zip_xy_scaler` or `&zip_xy_to_scroll_mapper` can also have new instances created with custom properties around which input codes to scale, or which codes to map, etc. -| Compatible | Processor | Description | -| --------------------------------- | ---------------------------------------------------- | ------------------------------------------------ | -| `zmk,input-processor-transform` | [Transform](transformer.md#user-defined-instances) | Perform various transforms like inverting values | -| `zmk,input-processor-code-mapper` | [Code Mapper](code-mapper.md#user-defined-instances) | Map one event code to another type | +| Compatible | Processor | Description | +| --------------------------------- | ---------------------------------------------------- | --------------------------------------------------- | +| `zmk,input-processor-transform` | [Transform](transformer.md#user-defined-instances) | Perform various transforms like inverting values | +| `zmk,input-processor-code-mapper` | [Code Mapper](code-mapper.md#user-defined-instances) | Map one event code to another type | +| `zmk,input-processor-behaviors` | [Behaviors](behaviors.md#user-defined-instances) | Trigger behaviors for certain matching input events | ## External Processors
