|
## Summary
|
|
|
|
The most basic of behaviors, is the ability to send certain keycode presses and releases in response to activating
|
|
a certain key.
|
|
|
|
The categories of supported codes are:
|
|
|
|
- [Keyboard & Keypad](../codes/keyboard-keypad.mdx)
|
|
- [Editing](../codes/editing.mdx)
|
|
- [Media](../codes/media.mdx)
|
|
- [Applications](../codes/applications.mdx)
|
|
- [Input Assist](../codes/input-assist.mdx)
|
|
- [Power](../codes/power.mdx)
|
|
|
|
Please visit the [codes](../codes/index.mdx) section for a comprehensive list.
|
|
|
|
For advanced users, user-defined HID usages are also supported but must be encoded, please see [`dt-bindings/zmk/keys.h`](https://github.com/zmkfirmware/zmk/blob/main/app/include/dt-bindings/zmk/keys.h) for further insight.
|
|
|
|
## Keycode Defines
|
|
|
|
To make it easier to encode the HID keycode numeric values, most keymaps include
|
|
the [`dt-bindings/zmk/keys.h`](https://github.com/zmkfirmware/zmk/blob/main/app/include/dt-bindings/zmk/keys.h) header
|
|
provided by ZMK near the top:
|
|
|
|
```dts
|
|
#include <dt-bindings/zmk/keys.h>
|
|
```
|
|
|
|
Doing so makes a set of defines such as `A`, `N1`, etc. available for use with these behaviors
|
|
|
|
## Key Press
|
|
|
|
The "key press" behavior sends standard keycodes on press/release.
|
|
|
|
### Behavior Binding
|
|
|
|
- Reference: `&kp`
|
|
- Parameter: The keycode usage ID from the usage page, e.g. `N4` or `A`
|
|
|
|
Example:
|
|
|
|
```dts
|
|
&kp A
|
|
```
