This section explains codes which control when, and if, text is to be placed on a new page.
For example, if there are only a few lines left on a page in which to fit a new text heading, you would not want that heading to appear on the last line of a page with the next paragraph beginning on the page following. You might not even wish just one or two lines of the next paragraph to follow the heading on the same page but prefer to start both heading and paragraph on a new page.
As a second example, many print books require all new chapters to begin consistently on an odd (right-hand) page. Others might require they start on an even (left-hand) page. The same may also apply in braille publications.
Similarly, in braille as in print, a Table of Contents would not normally appear on the back side of the Title page. Rather it would be forced to begin on the next odd (right-hand) page.
