• Create service(or ssh/screen/nohup...) so that you can use it in game mode

Functions

FN key	action	function
left bottom button	single click	steam menu
left bottom button	double click	gyro switch
left&right bottom button	single click	JS/mouse switch
right bottom button (not night mode btn)	single click	quick menu
right bottom button (not night mode btn)	double click	on-screen keyboard

• The events only been sent when you release the fn buttons, no events when you press them, so no long press actions
• Rumble not support yet.
