How to Enter Slideshow Mode in Google Slides

You need slideshow mode to present your work professionally without desktop distractions, menu bars, or editing tools cluttering the screen. Beyond basic presentations, this becomes essential when you're rehearsing timing, testing slide transitions, or sharing your screen during video calls. The full-screen environment lets you experience your content exactly as your audience will, helping you spot formatting issues, text that's too small, or slides that feel rushed when you're actually clicking through them at presentation pace.
