The ribbon is a set of toolbars at the top of the window in Office programs designed to help you quickly find the commands that you need to complete a task.
Show Ribbon options
At the top-right corner, select the Ribbon Display Options icon .
Choose an option for the ribbon:
Show Tabs and Commands keeps all the tabs and commands on the ribbon visible all the time.
Show tabs shows only the ribbon tabs, so you see more of your document, and you can still quickly switch among the tabs.
Auto-Hide ribbon hides the ribbon for the best view of your document, and only shows the ribbon when you select More , or press the ALT key.
Collapse the ribbon or expand it again
Double-click any of the ribbon tabs or press CTRL+F1 to collapse the ribbon if you need to see more of your document.
To see the ribbon again, just double-click any ribbon tab, or press CTRL+F1.
If the ribbon isn't visible at all
If the ribbon isn’t visible at all (no tabs are showing), then you probably have it set to Auto-hide. Select More at the top right of the screen. This will temporarily restore the ribbon.
When you return to the document, the ribbon will be hidden again. To keep the ribbon displayed, select one of the Show options above.
Minimize the ribbon
You can minimize the ribbon if you need to see more of the document you are creating. To collapse the ribbon, select the Minimize the Ribbon arrow at the top right.
To see the ribbon again, select the arrow again.
