Numbers file flips text in Table cells & Text boxes
Numbers version 10.3.5
macOS Big Sur 11.2.2
Something has happened such that when I type into a Table cell or a Text box, the letters flip.
They fill the box in reverse. Almost like I'm looking out of the monitor rather that at it.
When I type "United States" the cell or text box will enter "setatS detinU".
Have I inadvertently pressed some key sequence that has done this?
This affects a single Numbers file, but it happens in every tab of the file.
How do I reset/fix this?
