When going from your desktop to your presentation, you normally have to open the file, wait for PowerPoint to load, then click a button to open the file. If you’re about to start a presentation, this can be a waste of time.
Instead of waiting and clicking, you can make your PowerPoint files open directly in Slide Show mode, taking you from desktop to presentation in a flash.
From the desktop, right-click your PowerPoint file, then select Show from the drop-down menu. Your file will open in Slide Show mode, where you can present it. To leave your presentation, just press Escape to return to the desktop.
Watch the video below to see how quickly you can open a file in Slide Show mode.
