Many PowerPoint users like to start viewing presentations in slideshow mode, while discussing the content and keeping the conversation going. However, in some presentations, you may need to flip through multiple slides without any comments. Add a stopwatch effect to PowerPoint to automatically cycle through slides with just a few clicks. See step 1 to get started!
