Review and Reset Keyboard Shortcuts and Macros

Custom keyboard shortcuts or macros might be conflicting with the default Undo or Redo commands, triggering a document close action instead.

If you frequently switch between files, macro bindings or customized shortcuts can sometimes misfire or map to the 'Close' command instead of 'Undo' or 'Redo'.

1
Open Word Options

Launch Word 2016, click on the 'File' tab in the top-left corner, and select 'Options' from the bottom of the left menu.

2
Access Ribbon Customization

In the Word Options dialog box, select 'Customize Ribbon' on the left panel, then click the 'Customize...' button next to 'Keyboard shortcuts:' at the bottom.

3
Reset Keyboard Shortcuts

In the Customize Keyboard dialog, look for the 'Reset All' button at the bottom right. Click it to restore all shortcuts to their default settings, ensuring Ctrl+Z (Undo) and Ctrl+Y (Redo/Repeat) function correctly.

4
Disable Conflicting Macros

Go to the 'View' tab, click on 'Macros', and review any active macros. Delete or edit any macros that are assigned to the Undo or Redo keys.

Review and Reset Keyboard Shortcuts and Macros
Default shortcuts restored: Resetting keyboard shortcuts will clear any unwanted custom bindings and restore the standard Undo and Redo behaviors.

Frequently Asked Questions

Why does Ctrl+Z close my Word document instead of undoing?

This typically happens if the Ctrl+Z shortcut was accidentally mapped to the 'Close' command in the Customize Keyboard settings, or if a macro is intercepting the keystroke. Resetting your keyboard shortcuts to default will resolve this issue.

Does Office 2016 still get new features to fix these issues?

No, Office 2016 is in its extended support phase and only receives security updates and critical bug fixes. It does not receive new feature enhancements or major functional overhauls found in newer versions.

What is the difference between Redo and Repeat in newer Word versions?

In current versions, the Redo command (Ctrl+Y) reverses an Undo action. If no action has been undone, the same shortcut acts as a Repeat command, which duplicates your last editing action, such as applying formatting or inserting text.
