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 Word Web App Ribbon looks like when a word document is created or edited.
As can be seen, components such as Format Painter and Text Effects are missing compared to the full Word Office Ribbon. However should one or more of these components be required, there is the Open in Word button on the far right which will load the document into the full version of Word on your computer. The Insert and View Ribbons are shown below.
On first glance it does seem as if the Home, Insert and View ribbons have too much functionality missing, however Word Web App also displays contextual Ribbons in a similar method to the full version of Microsoft Word 2010.
Let's take two scenarios to illustrate Word App's contextual Ribbons. If we were to click Insert: Picture, then the Picture Tools Format Ribbon would appear.
The Format Ribbon will stay while the picture is selected, to make the Format Ribbon disappear, we would click back into the document. Finally if we were to click Insert:Table, the Table Tools Layout Ribbon would appear and would stay in view while the table is selected.
As can be seen in the Table Tools Layout Ribbon screen shot, extra functionality to help edit a table is now available. To make this Layout Ribbon disappear, we would click back into the document. Finally to print or save the document, we would click on the File Menu on the left.
