Mouse & Keybord functionality over ARD

Dear readers and professionals

Is it possible to add mouse and keyboard functionality over ARD to ATV?
I would like to do some tasks over ARD but right now I’m not able to use the mouse or the keyboard.
Do I have to install AirMouse or any other tool to get this working?
How can I set this functionality to work all the time, even after restart?

Thank you for your feedback.
Kind regards
Thomas Thaler
