The Outline view is new for PowerPoint 2013 — wait, that’s not absolutely true since you always had access to your presentation’s text outline through the Slides / Outline pane on the left side of the PowerPoint interface. What’s changed though is that you no longer need to switch tabs within the pane (as you would do in PowerPoint 2010) — now you just access the outline within a new view! The Outline view displays all the text contained within the title and text placeholders of your slides, and is one of the ten views in PowerPoint 2013 for Windows.
