What you can customize: You can personalize your ribbon to arrange tabs and commands in the order you want them, hide or unhide your ribbon, and hide those commands you use less often. Also, you can export or import a customized ribbon.
What you can't customize: You can't reduce the size of your ribbon, or the size of the text or the icons on the ribbon. The only way to do this is to change your display resolution, which would change the size of everything on your page. You can't change the color of the ribbon, or its icons, but you can change the color scheme that Office uses throughout. For more information see Change the Office theme.
When you customize your ribbon: Your customizations only apply to the Office program you're working in at the time. For example, if you personalize your ribbon in Word, those same changes won't be visible in Excel. If you want similar customizations in your other Office apps, you'll have to open each of those apps to make the same changes.
Open Word.
**To Hide the ribbon** In the top right corner of the app, choose the **^**.
**To display the ribbon** Choose a tab. When the ribbon expands, choose the to pin the ribbon to the top so it stays there.
If you're using Read Mode, press the Esc key to display your ribbon.
To open Customize the Ribbon and keyboard shortcuts window
Go to **File** > **Options** > **Customize the Ribbon**.
Notes: To save time, you can do multiple additions and changes while the window is open, and only save when you're done.
To save your changes and see the results, select **OK** in the customize window.
You can add custom tabs or groups to put additional commands on the ribbon, or replace default tabs with your own versions. Custom tabs and groups have (Custom) after the name in the Customize the Ribbon window, but the word (Custom) does not appear in the ribbon.
A custom group can be added to either a default or a custom tab.
