I am not a writer by profession, but if you do some type of writing for work, school or fun you learn a few things over time. One thing I have always used over the years is Em Dashes, En Dashes and Hyphens. A Hyphen is just the dash key on your keyboard. Em and En Dashes can come in handy when stylizing text in your document. This article explains what all these dashes are and how they may be used. That is no big deal I guess, but if you do any kind of writing at all you may end up using them from time to time.
