The ribbon is usually fully visible.
However, you can hide the ribbon at any time by minimizing it. This is useful if you want to have as much screen space as possible to display the document.
Proceed as follows:
| 1. | Click on the black arrow to the right of the Quick access toolbar. |
| Alternatively: Right-click on anywhere in the ribbon. |
| 2. | A menu opens. It contains the option Minimize the Ribbon, which can be enabled or disabled via a mouse click. (A check mark appears in front of the option if it is currently enabled.) |
After you enable this option, the ribbon will be minimized. Only the ribbon tabs and the Quick access toolbar will then be seen.
Tip: Alternatively, you can click on the icon 
in the lower right corner of the ribbon to minimize the ribbon. Alternatively, simply use the shortcut key Ctrl+F1.
Working with a minimized ribbon
You work with a minimized ribbon as follows:
▪When you click on one of the ribbon tabs of the minimized ribbon, the ribbon becomes completely visible again temporarily and displays the corresponding ribbon tab. As soon as you trigger a command (for example, click on the icon for a command), however, the ribbon will be automatically minimized again.
▪If you double-click on one of the ribbon tabs, the ribbon will be will be permanently visible again, thus removing the minimization.
