I often display documents or spreadsheets to small groups during working meetings.  When doing so, I want to maximize the amount of content I am displaying.  One easy way to do this is to collapse the ribbon tool bar.  There are a couple of ways to do this:

1. Double-click on any of the tabs (except “File”) in the ribbon.
2. Select the “Minimize the Ribbon” icon in the upper-right hand corner or the application window, beside help.  Once you minimize the ribbon, the icon will change to “Expand the Ribbon”.

Once the ribbon is collapsed, you can single-click on a tab and the menu options for that tab will appear to select one option.  Once you select an option, the tool bar collapses again.

Or, you restore the ribbon by either double-clicking on a tab or selecting the “Expand the Ribbon” icon.
