  4. To test whether your PowerPoint can loop successfully, click on the "From Beginning" or "Play From Start" button in the Slide Show tab. Click through the slideshow until you reach the end. When your PowerPoint reaches its final slide, it should start over from the beginning automatically. When you're confident that looping is enabled, and you're ready to close the slide show, press the Esc key.
