@ -21,7 +21,11 @@ Keep in mind that a report_mouse_t (here "mouseReport") has the following proper
* `mouseReport.h` - this is a signed int from -127 to 127 (not 128, this is defined in USB HID spec) representing horizontal scrolling (+ right, - left).
* `mouseReport.buttons` - this is a uint8_t in which the last 5 bits are used. These bits represent the mouse button state - bit 3 is mouse button 5, and bit 7 is mouse button 1.
When the mouse report is sent, the x, y, v, and h values are set to 0 (this is done in "pointing_device_send()", which can be overridden to avoid this behavior). This way, button states persist, but movement will only occur once. For further customization, both `pointing_device_init` and `pointing_device_task` can be overridden.
Once you have made the necessary changes to the mouse report, you need to send it:
* `pointing_device_send()` - Sends the mouse report to the host and zeroes out the report.

In the following example, a custom key is used to click the mouse and scroll 127 units vertically and horizontally, then undo all of that when released - because that's a totally useful function. Listen, this is an example:
