Change Underlining to Italics
This option changes text that is underlined into text that is italicized. In the days before word-processing, people used typewriter underlining to indicate text that was to be set in italics. Some writers, even though they are now composing on computer, still continue in that tradition. Underlining, however, should not ordinarily be used in typesetting, and this option allows you to turn it into italics as it should be.
