We don't want any cell in the grid to get focus, but we need to be able to allow the user to scroll up and down.

Things already tried:
grid.when return .f. - can't scroll up and down.

put shape over grid covering everything but the scroll bar - when the user clicks on the scroll bar, cell 1 column 1 gets focus.

What am I missing? I don't want to see any highlight at all on the grid, but still allow the user to scroll.
