Question details

The user wants to stop Microsoft Word for Mac from overwriting existing text when typing.

Product
Microsoft Word
Device & OS
Mac
Scenario
Typing or editing a document.
Observed behavior
Typing replaces the character or space to the right of the cursor instead of inserting new text.
Before you start

Ensure that your Mac keyboard doesn't have a stuck 'Insert' (Ins) key, which can accidentally trigger the overtype function in word processors.

Solution 1Recommended

Disable Overtype Mode in Word Preferences

The most common reason for this issue is that Overtype Mode has been accidentally enabled in your Word preferences. Turning this off will restore normal text insertion.

By default, Microsoft Word uses 'Insert Mode', which pushes existing text to the right as you type. If 'Overtype Mode' is turned on, new characters will delete and replace the characters immediately to the right of the cursor.

1
Open Word Preferences

Click on 'Word' in the top Apple menu bar, then select 'Preferences' from the dropdown menu.

2
Navigate to Edit Settings

In the Preferences dialog box, locate and click on the 'Edit' icon.

3
Turn off Overtype Mode

Find the checkbox labeled 'Replace existing text as you type (Overtype Mode)' and clear it. Close the Preferences window to save your changes.

Disable Overtype Mode in Word Preferences
Typing Restored: Your cursor will now insert text normally without deleting the characters to the right.

Frequently Asked Questions

Why did my Word suddenly start replacing text?

You likely accidentally pressed the 'Insert' key on your keyboard or clicked the 'Overtype' indicator on the status bar. This switches Word from standard insertion to Overtype mode.

How do I know if Overtype mode is active?

When Overtype mode is active, typing new letters will instantly erase the text immediately to the right of your cursor. You may also see the word 'Overtype' displayed in the status bar at the bottom of the Word window.

Can I permanently disable the Insert key shortcut in Word?

Yes. In Word Preferences under the Edit menu, you can uncheck 'Use the Insert key to control overtype mode' to prevent accidental toggling in the future.
