If you insert a blank page between two paragraphs in, for purposes of illustration, a single-page document, the subsequent paragraph will appear on page three following the inserted blank page.

If , instead, you insert a page break, the subsequent paragraph will be on page two; no blank page will have been inserted.

This is easier to see if you turn on hidden characters, (press Ctrl+*) so that you can see the breaks.

Best,
