To access this setting, do the following: Figure A Word alerts you to the spacing error. (To see the space and paragraph characters, click Show/Hide in the Paragraph group on the Home tab.) This setting is a visual alert, not an automated fix. As you can see, when the number of spaces doesn't match the setting, Word displays a red dotted line below the spaces.
The settings don't undo or redo anything instead, the two settings display a grammar error when you don't type the expected number, as shown in Figure A.
