One of the most important parts of the interface within PowerPoint for iPad is the Ribbon – a typically orange area that sports Tabs with options and commands. Now this Ribbon works almost the same in PowerPoint for iPad as it does in PowerPoint instances anywhere. The main difference here is that you will have to tap to make something happen rather than click! Of course, since the options available on the iPad are fewer, you end up with a thinner, more compact Ribbon as well.
