Moving to the previous slide during a PowerPoint presentation is just a right-click away.
If you right-click during a slide show, PowerPoint displays a list of slide show options. Whether you'll use these options during an actual presentation is debatable. They certainly make improvising simpler, but then again, you might never use them. If you can easily live without these options, you can inhibit the list and gain a bit of maneuverability in the bargain.
You see, many versions ago, a right-click displayed the previous slide. That functionality was replaced with the options list in PowerPoint 97 -- it's just a default setting, though. It's a simple matter to get rid of the options list so you can use the right-click to move to the previous slide. You can reset this default as follows:
Once you clear this option, PowerPoint will move to the previous slide when you right-click during a slide show.
- Choose Options from the Tools menu and click the View tab. In PowerPoint 2007, click the Office button and select Advanced in the left pane.
- Uncheck the Show Menu On Right Mouse Click option in the Slide Show section.
- Click OK.
