Hi Oliver,

I understand your frustration with this issue. It sounds like the "Overtype" mode is turned on in your Word program. This mode allows you to type over existing text, rather than inserting new text before it. Here's how you can turn it off:

1. Open Microsoft Word.
2. Click on the "File" tab in the top left corner.
3. Click on "Options" at the bottom of the left-hand menu.
4. Click on "Advanced" in the left-hand menu.
5. Scroll down to the "Editing options" section.
6. Uncheck the box next to "Use overtype mode".
7. Click "OK" to save the changes.

This should solve the issue with the highlighted text not being deleted when you start typing or press the backspace key.

Let me know if this helps or if you have any further questions!
