You've never worked in Normal view? Note that the "dash" I'm talking about
is a short, heavy black line at the bottom left margin of the document. It
will not move with the insertion point. If you have something that moves
with the insertion point, then it's something else. It is especially handy
for people who don't display nonprinting characters because it indicates
where the end of the document is. If you've got dozens of empty paragraphs
below your last line of text (which will ultimately result in an extra,
blank page being "printed"), you'll see a lot of space between your text and
the end-of-document marker. Or if you have added Spacing Below to your
paragraph, you'll see that space between the paragraph mark (or insertion
point) and the EOD marker.
