How to Fix Custom Word Shortcuts Using Alt Keys That Stop Working in Word
Product
Microsoft Word
Device & OS
not provided
Scenario
Using custom keyboard shortcuts to run specific commands in a Word document efficiently.
Observed behavior
Custom shortcuts using Alt-number combinations work inconsistently or fail entirely after reopening a document, while letter-based shortcuts like Alt+A continue to function normally.
Before you start

Verify if the issue is isolated to a specific document or if it affects all new blank documents. Ensure no other applications running in the background are capturing your keystrokes.

Solution 1Recommended

Reassign Custom Commands to Alternative Modifier Keys

Avoid using Alt+Number and Ctrl+Alt+Number combinations, as they inherently conflict with built-in Word KeyTips and heading shortcuts.

Microsoft Word reserves Alt+1 through Alt+9 for Quick Access Toolbar (QAT) KeyTips, and Ctrl+Alt+1 through 3 for default heading styles. Assigning custom commands to these keys often results in inconsistent behavior.

1
Access Word Options

Open Microsoft Word, navigate to the 'File' menu, and click on 'Options' at the bottom.

2
Open Keyboard Customization

Select 'Customize Ribbon' from the left pane, then click the 'Customize' button next to 'Keyboard shortcuts' at the bottom of the window.

3
Reassign the Shortcut

Locate the command you want to customize. In the 'Press new shortcut key' box, enter a combination that uses 'Ctrl' or 'Ctrl+Shift' instead of 'Alt' (e.g., Ctrl+Shift+1).

4
Save Changes

Click 'Assign' and ensure the 'Save changes in' dropdown is set to Normal.dotm so the shortcut persists across all new documents.

Reassign Custom Commands to Alternative Modifier Keys
Best Practice: Using Ctrl or Ctrl+Shift for custom shortcuts is generally safer and less likely to conflict with Windows or Office system-level commands.

Frequently Asked Questions

Why does Alt+1 open the Quick Access Toolbar instead of my custom command?

By default, Microsoft Office reserves Alt+1 through Alt+9 as KeyTips to quickly trigger commands pinned to your Quick Access Toolbar (QAT). This built-in function typically overrides custom shortcut assignments utilizing those specific keys.

Can I disable Word's default KeyTips to use Alt+ keys freely?

Microsoft Word does not provide a built-in toggle to completely disable KeyTips. To avoid unpredictable behavior, it is highly recommended to use different modifier keys like Ctrl or Ctrl+Shift for your custom shortcuts.

What is Normal.dotm and why does it affect my keyboard shortcuts?

Normal.dotm is the default template that Word uses to create blank documents. All custom keyboard shortcuts, macros, and styles are typically saved here. If this file becomes corrupted, your saved custom shortcuts may fail to load properly.

Why do my custom shortcuts work in a new document but stop after I reopen Word?

This inconsistency usually happens because changes made to your custom shortcuts were not successfully saved to the Normal.dotm template upon closing Word, or an active add-in is intercepting the keystrokes when the application reloads.
