If you have two blocks on the same row, you can add a block directly below by clicking the shorter insert point.
Did you see those boxes appear? That means you can float that box. Maybe this is a quote.
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Morbi eget sapien sed risus suscipit cursus. Quisque iaculis facilisis lacinia. Mauris euismod pellentesque tellus sit amet mollis. Nulla a scelerisque turpis, in gravida enim. Pellentesque sagittis faucibus elit, nec lobortis augue fringilla sed. Donec aliquam, mi in varius interdum, ante metus facilisis urna, in faucibus erat ex nec lectus. Cras tempus tincidunt purus, eu vehicula ante. Duis cursus vestibulum lorem.
By looking for that smaller line that was the same height as the Image--I created a row.
