Sometimes you want to run a PowerPoint presentation on repeat – looping the slideshow so it can play in the background during an event, perhaps at a booth at a tradeshow. Is it possible to automatically loop a slideshow in PowerPoint? Yes! In PowerPoint 2013, it’s easy.
A slide master is a part of a PowerPoint template that controls how slides appear throughout your presentation. When you make changes to a slide master, they’re applied universally to the presentation. Make a change once – and it’ll appear everywhere it’s supposed to!
