In MS PowerPoint users can save their presentations as a PowerPoint Show instead of a PowerPoint Presentation.
Besides changing the file extension from
.ppsx, this option means that upon opening the file it will automatically open in Slideshow mode rather than the typical PowerPoint editing mode. It also means the Slideshow can start playing automatically, so that it moves from slide to slide without user input (if it's been designed to do that).
Is there a similar feature in the Keynote app for macOS? If so, how do I use it?
