Keynote 
Change to a links-only or self-playing presentation
By default, your presentation is set to advance when you click a slide. You can set the presentation to advance only when you click a link, or to advance automatically with no user interaction.
You can also set your presentation to start playing automatically when the Keynote file is opened.

Click the Presentation Type pop-up menu, then choose an option:
Normal: Advances when you click or tap a slide.

Self-Playing: Advances automatically, like a movie, with no interaction needed. Self-playing presentations are useful, for example, in a kiosk setting.
