Working with the Outline
You can work on an outline in the Outline tab in the Slides/Outline pane displayed at the left of the Slide pane in Normal view. The Outline tab lets you compare the outline with slides, which might include graphics or text boxes that don’t show up in the outline. Entering text in the outline can be faster than entering it on individual slides when you’re focused purely on presentation text content.
