Hi,
Here are some steps and considerations to help you address this issue:
- Make sure that you have thoroughly reviewed the worksheet protection settings. Check the "Format cells" option in particular. If you do not select this option when protecting the sheet, the cursor movement may be affected.
- Navigate to "File" > "Options" > "Advanced" and enable the "Transition navigation keys" option. Make sure it's set to "Directional."
- Make sure that your Excel version is up to date by applying any available updates or service packs.
- Create a new Excel workbook with a similar structure and test the protection settings and cursor behavior there. This can help determine if the issue is specific to your existing workbook or a more general Excel behavior.
Best Regards.
