UNDERLIN allows you to underline each line of text with a
line extending from the first character to the end
character.

Indicate whether or not you want to underline the text. If
you choose NO, the text is not underlined. If you choose
YES, form this point on, all newly created notes and 
labels are underlined. If later you want to stop 
underlining the text, choose UNDERLN and indicate NO.
