Example of use.

You have cropped caller video. He move left/right during the show. Now to fix position you need change cropX1 and cropX2 and pan input. And must do it on good precision so you not go out frame you have made.
With shortcut you can do it on one button.

{Caller is in input 3 index 2(multiview two)}

Add button with three change in one click.
