Windows The full edit and presentation shortcut set. F5 starts the slideshow from the beginning; Shift+F5 from the current slide. F-keys work without Fn. Alt activates Ribbon navigation for any command. During presentation: B for black screen, W for white screen, Escape to end.
Mac Uses Command (⌘) as the primary modifier. F5 requires Fn+F5 by default on Mac to start a slideshow — or you can change F-key behavior in System Settings. Presentation delivery shortcuts (B, W, Escape, arrow keys) work the same as on Windows once the show is running.
Web on Mac Browser-based PowerPoint on macOS. Uses Command as the modifier. Most edit-mode shortcuts work; presentation delivery in the browser may differ from the desktop app experience.
Web on Windows Browser-based PowerPoint on Windows. Uses Ctrl as the modifier. Same web app as the Mac browser version with the modifier key swap.
iPhone Requires an external keyboard. Covers edit-mode shortcuts — formatting, navigation — on iPhone. Presenting from a phone is less common but the shortcut reference covers what's available.
Android Requires a Bluetooth keyboard. Uses Ctrl as the modifier. Coverage similar to iPhone.
