Amlogic remote control mouse button adaptation

First, describe the function. After the reserved mouse button is configured on the remote control, the function is realized by pressing the mouse button. The icon of the left mouse button appears on the TV screen. The direction navigation controls the movement direction up, down, left, and right. Click the mouse button again To restore the default functions of the remote control.

Below, I randomly found a remote control and changed the button to mouse button
