Isn't it frustrating when you're typing and your new words start deleting the words already on the page? You might be thinking your PC's been hacked, but the issue is usually that you've pressed the Ins (Insert) key on the keyboard. This wikiHow teaches you how to toggle on/off overtype mode—the mode that makes your new letters replace existing ones—as well as how to disable it completely in Microsoft Word.

Method 1

Method 1 of 2:
Toggling Off Overtype Mode with the Insert Key

1
Press Insert or Ins once. The key is usually near the top-right corner of the keyboard. Pressing this key toggles the Insert function on or off in any app on your PC.
2
Press Ctrl+Z to restore accidentally-deleted text. You may have to press this key combination to undo all of the text you've accidentally replaced.
3
Type your text again. Now that you've pressed the key, you should be able to type without erasing what's already on the page.
- If you're using Microsoft Word and find yourself accidentally pressing the ⌤ Ins key too often, you might want to disable overtype mode. See the Disabling Overtype Mode in Microsoft Word method to learn how.
- If you're still having trouble entering new text, save your work and close the application. When you restart the app, you should be able to type text normally.
