When you type a space and one or two hyphens between text, Microsoft Office Word automatically inserts an en dash ( – ). For example, if you type See pages 3 <hyphen> 10, Word converts it to See pages 3 – 10.
If you type two hyphens and do not include a space before the hyphens, an em dash ( — ) is created. For example, if you type Many pines <hyphen><hyphen> including ponderosa and lodgepole <hyphen><hyphen> grow here Word converts it to Many pines—including ponderosa and lodgepole—grow here.
