Scrolls one page down so that the last line (truncated or whole)
of the current page becomes the fully visible top line.
<p>
The caret is scrolled the same number of lines so that its location
relative to the top line remains the same. The exception is the end
of the text where a full page scroll is not possible. In this case
the caret is moved after the last character.
