Two Miniature Views
The Slides/Outline pane is located on the left side of the PowerPoint 2007 screen.
The default setting is for Slides. This shows thumbnail views of the slides in your presentation.
Clicking on the Outline tab, will show a text outline of each slide in your presentation.
Note that each time you add a new slide, a miniature version of that slide appears in the the Slides/Outline Pane on the left side of the screen. Clicking on any of these thumbnails, places that slide on the screen in Normal View for further editing.
