Many new changes have happened within PowerPoints 2013 — but the tri-paned interface has still not changed a lot for the last 20 years and successive PowerPoint versions! So why is the interface called tri-paned — are there three distinct regions within the PowerPoint 2013 interface? Yes — the Slide area is one of three principal regions in PowerPoints 2013 — the other two are the Slides pane and the Notes pane. The Slide area is where you work the most — typically though adding and editing slide objects.
