Cannot navigate out of cell using arrow keys - again

The cursor in my spreadsheet has become ‘stuck’ in one cell and won’t move from it using (e.g.) arrow keys or page up/down. The navigation operated normally when I opened the spreadsheet. Instead now if I ‘arrow left’ the cursor remains in the initial cell instead of moving the one on its left - instead the underlying grid of cells moves one column to the left. :confused:

Have I maybe ‘fat-fingered’ a shortcut setting somehow? This has happened before (I had to lose my changes and reload my spreadsheet).

Using Win10 and LibreOffice 7.0.5.2. The spreadsheet has been converted from Excel

I have looked through all the settings, help and this help forum. Would very much appreciate an answer. Many thanks!
