Sending e-mail is the only place I have noticed it.

Answer 1

Hold shift then press return :-)

Answer 2

When you compose in Yahoo, do not hit "return" at the end of a line. Text will "wrap" to fit the screen.

In Word, you set your margins and do not hit "return" at the end of a line. For single spacing, Select all, then click Format, Paragraph. Toward the right, see "line spacing." Click the down arrow and select "single." To the right of that, type 1, then click o.k.

You didn't specify which application you were using. Look for a Format menu and a Font or Paragraph option.
