How to Restore Ctrl+0 for Paragraph Spacing in Microsoft Word
Question details
The user wants to reassign the Ctrl+0 keyboard shortcut to toggle paragraph spacing in Microsoft Word, as recent updates changed its default behavior.
- Product
- Microsoft Word
- Device & OS
- not provided
- Scenario
- Customizing keyboard shortcuts to restore legacy formatting functionality in Microsoft Word.
- Observed behavior
- Pressing Ctrl+0 triggers the Zoom100 command (adjusting the document zoom to 100%) instead of the OpenOrCloseUpPara command (adding or removing paragraph spacing).
Ensure you have Microsoft Word open, preferably with a blank document, before proceeding to modify your global keyboard shortcuts.
Customize Keyboard Shortcuts in Word Options
Remove the default Zoom command assignment and manually map Ctrl+0 back to the paragraph spacing command.
In newer installations of Microsoft 365, the Ctrl+0 shortcut has been reassigned to zoom functions. By accessing the Word Options menu, you can remove this new binding and restore the classic OpenOrCloseUpPara function.
Launch Microsoft Word. Click on 'File' in the top-left corner of the screen, and select 'Options' from the bottom of the left-hand menu.
In the Word Options dialog box, click on 'Customize Ribbon' in the left pane. Then, locate 'Keyboard shortcuts' at the bottom of the right pane and click the 'Customize' button next to it.
Under the 'Categories' list, scroll down and select 'View Tab'. In the 'Commands' list on the right, select 'Zoom100'. Click on 'Ctrl+0' in the 'Current keys' box, and then click the 'Remove' button.
Go back to the 'Categories' list and select 'Commands Not in the Ribbon'. In the 'Commands' list, find and select 'OpenOrCloseUpPara'. Click inside the 'Press new shortcut key' box, press 'Ctrl+0' on your keyboard, and click 'Assign'.
Click 'Close' and then 'OK' to exit the options. If Word prompts you to save changes to the Normal template when you close the application, be sure to accept it so the shortcut works in all future documents.

Frequently Asked Questions
Why did my Ctrl+0 shortcut stop working for paragraph spacing?
In recent Microsoft 365 updates, Microsoft changed the default behavior of the Ctrl+0 shortcut, reassigning it to the Zoom 100% command. You must manually customize your keyboard shortcuts to restore the original functionality.
What is the OpenOrCloseUpPara command in Microsoft Word?
OpenOrCloseUpPara is the internal Word command that toggles between adding 12 points of spacing before a paragraph and removing it. It was traditionally mapped to the Ctrl+0 keyboard shortcut.
Do I have to reassign the Ctrl+0 shortcut every time I open Word?
No. As long as you save the keyboard shortcut modifications to the Normal template (Normal.dotm) when prompted, your custom Ctrl+0 shortcut will persist across all new documents.
