Two Kinds Of Page Break

Hi,

In Normal View, I see two kinds of ordinary page breaks.  One has the
words
'Page Break' in the middle of the window with the dotted lines running
equally on each side of the words, and all the way to the side of the
window.

The other kind in Normal View is ****fted to the right.  The words "Page
Break" are placed as though in the center of the right colume of a three
colume page.  The dotted line on the right of "Page Break"  runs and ends
at
the right side of the window.  The dotted line on the left ends in the
middle of the window.

What is the difference between these two formats of 'Page Break'?

Thanks
