If the column-selection is not zero-width, it should be legit (like replacing X with an empty string).

If you're not in column-selection, pressing OK should not modify the file.
But it does: Undo is active, and you get Changed History markers.
Do you understand why?

Nah, too obscure. Just press Delete key, don't even invoke Column Editor at all.

Nope.
