Only 2 options I can choose if use Keynote:ġ. And this function in powerpoint is fine.(2 screens are exactly same and in mirror, all actions and shows are same and synchronized.)
Since when I give a lecture to my students, it is better to use Presenter Display then I can see slide notes, and when I move cursor to point something in Macbook, I hope the cursor can move in Projector synchronously in mirror, if not I have to move the cursor into projector and then my sight have to move to projector too, but the projector is in my back you may know, this is very inconvenient I have to have my sight moved between Macbook and projector Back and forth. In Presenter Display and don't use Mirror Displays, I need the keynote slide in Presenter Display are exactly same with projector screen, that is to say 2 slides in 2 displays are in mirror, include the cursor.
