Collapse or Expand the PowerPoint 2007 Outline
If your PowerPoint presentation has many slides, you might find its overall structure is difficult, to understand. Fortunately, PowerPoint enables you to collapse the PowerPoint outline so that only the slide titles are shown. Collapsing an outline doesn’t delete the body text; it merely hides the body text so that you can focus on the order of the slides in your presentation.
Expanding a presentation restores the collapsed body text to the outline so that you can once again focus on details. You can collapse and expand an entire presentation, or you can collapse and expand one slide at a time.
To collapse the entire presentation, right-click anywhere in the outline and then choose CollapseCollapse All or use the keyboard shortcut Alt+Shift+1.
To expand the presentation, right-click and choose ExpandExpand All or press Alt+Shift+9.
To collapse a single slide, right-click anywhere in the slide and then choose CollapseCollapse from the menu that appears.
To expand a single slide, right-click the collapsed slide and choose ExpandExpand.
