Which shortcut key is used to start a presentation from the beginning in PowerPoint?

In Microsoft PowerPoint, pressing the F5 key is the standard shortcut to start a presentation from the beginning, no matter which slide you’re currently on. This is especially useful when you want to preview your entire slideshow from the very first slide.

PowerPoint includes many shortcut keys to enhance productivity during presentations, and F5 is one of the most commonly used for starting or rehearsing slide shows.
