+title: Mouse Emulation Behaviors
+sidebar_label: Mouse Emulation
+---
+
+## Summary
+
+Mouse emulation behaviors send mouse events. Currently, only mouse button presses are supported, but movement
+and scroll action support is planned for the future.
+
+:::warning[Refreshing the HID descriptor]
+
+Enabling or disabling the mouse emulation feature modifies the HID report descriptor and requires it to be [refreshed](../../features/bluetooth.md#refreshing-the-hid-descriptor).
+The mouse functionality will not work over BLE until that is done.
+
+:::
+
+## Configuration Option
+
+This feature can be enabled or disabled explicitly via a config option:
+
+```
+CONFIG_ZMK_MOUSE=y
+```
+
+If you use the mouse key press behavior in your keymap, the feature will automatically be enabled for you.
+
+## Mouse Button Defines
+
+To make it easier to encode the HID mouse button numeric values, include
+the [`dt-bindings/zmk/mouse.h`](https://github.com/zmkfirmware/zmk/blob/main/app/include/dt-bindings/zmk/mouse.h) header
+provided by ZMK near the top:
+
+```
+#include <dt-bindings/zmk/mouse.h>
+```
+
+## Mouse Button Press
+
+This behavior can press/release up to 5 mouse buttons.
+
+### Behavior Binding
+
+- Reference: `&mkp`
+- Parameter: A `uint8` with bits 0 through 4 each referring to a button.
+
+The following defines can be passed for the parameter:
+
+| Define        | Action         |
+| :------------ | :------------- |
+| `MB1`, `LCLK` | Left click     |
+| `MB2`, `RCLK` | Right click    |
+| `MB3`, `MCLK` | Middle click   |
+| `MB4`         | Mouse button 4 |
+| `MB5`         | Mouse button 5 |
+
+Mouse buttons 4 and 5 typically map to "back" and "forward" actions in most applications.
+
+### Examples
+
+The following will send a left click press when the binding is triggered:
+
+```
+&mkp LCLK
+```
+
+This example will send press of the fourth mouse button when the binding is triggered:
+
+```
+&mkp MB4
+```
