Sorry, I am very new at this. I first select my sideshow from my menu, then select (from the edit menu to the left) edit movie. This brings up sideshow assistant. The only options at the top of this screen is - preview, remove, rotate, view as, edit text & add blank slide. If I select "next" at the bottom of the screen, the options I have at the top are the same except pan & zoom & add narration.
