Each ribbon is accessed by clicking on the tab at the top of the current ribbon. The new ribbon contents display options particular to that ribbon.
For example, the Design ribbon displays options that pertain to the design aspects of the PowerPoint presentation, such as themes and fonts.
The Home ribbon contains the Layout option for you to choose which layout is best for the slide you are working on.
Note - The appearance of any of the new Ribbons may vary depending on the resolution of your computer monitor. If you use a wide screen monitor, more options will be visible on the Ribbon without having to click the drop down button.
