What keyboard shortcut is used to start a slideshow from the beginning?

Starting a slideshow from the beginning in PowerPoint can be quickly accomplished using the F5 keyboard shortcut. This shortcut is designed specifically for this function, allowing users to begin their presentations efficiently without navigating through menus. When pressed, it automatically displays the first slide of the current presentation on the screen, making it an essential tool for presenters.

The other keyboard shortcuts mentioned serve different purposes. For instance, Ctrl + S is typically used to save your work, Alt + P does not have a standard function related to starting a slideshow, and Shift + F5 starts the slideshow from the current slide, rather than from the beginning. Understanding these specific functions can enhance your PowerPoint efficiency and overall presentation skills.
