Start or End a Self-Running PowerPoint 2007 Presentation
You’ve designed your PowerPoint slides and set your presentation to be a self-running presentation. Now What? PowerPoint provides these handy techniques for starting a self-running, kiosk-style presentation:
On the Slide Show tab, click the From Beginning button (or press F5).
Click the Slide Show view button.
Self-running presentations loop when they are finished playing. You return to the first slide and start all over. The controls in the lower-left corner aren’t there for clicking. The keyboard shortcuts for getting from slide to slide are inoperable.
To end a self-running presentation, press Esc.
