Please remember that the document applies to both nroff and troff. For nroff (terminals, printers), .ul does underlining. For typesetters (includes laser printers) troff .ul does italics. The .us macro shows how to get real underlining on a typesetter device. Evolution plays a part here. The original formatter was nroff for printers and teletypes. Troff came along later, at which point .ul was already in use in people's documents and/or macro packages. HTH, Arnold
