The Office Web Apps use the same Ribbon method introduced in Office 2007 to display their functionality. Unlike Microsoft Office 2007 and Microsoft Office 2010, the Web Apps have reduced functionality and are sometimes known as Office Light. In some senses, this reduced functionality is a boon to many who became confused with the variety of rarely used commands that now adorn the Ribbon of the full Microsoft Office versions.
This is what the PowerPoint Web App Ribbon looks like when a presentation is created or edited:
As can be seen, components such as Drawing Tools, Animations and Transitions are missing compared to the full PowerPoint Office Ribbon. However, should one or more of these components be required, there is the Open in PowerPoint button on the far right, which will load the presentation into the full version of PowerPoint on your computer. The Insert and View Ribbons are shown below:
On first glance, it looks as if the Home, Insert and View ribbons have too much functionality missing, but the PowerPoint Web App also displays contextual ribbons in a similar method to the full version of Microsoft PowerPoint 2010.
Let's take two scenarios to illustrate this. If we click Insert > Picture, then the Picture Tools Format Ribbon appears.
The Format Ribbon will stay in view while the picture is selected. To make the Format Ribbon disappear, we would click back into the presentation.
If we click Insert > SmartArt, the SmartArt Tools SmartArt Ribbon appears and stays in view while it's selected. As can be seen below, extra functionality to customise the SmartArt is now available.
To make the SmartArt Ribbon disappear, we would, again, click back into the pesentation. Finally, to print or close the document, we would click on the File Menu on the left.
Unlike the Word Web App, the PowerPoint Web App saves as you type. This is a real bonus as it protects users from losing work, should, for whatever reason, they lose the internet connection. For similar overviews, see the Word Web App Ribbon and the Excel Web App Ribbon articles.
