In the fall of 1986, I was a freshman in college, and my first term paper was due. Daunted by the thought of attempting the typewriter, I made an emergency purchase of my very first computer (a Mac 512KE, signed by Steve Jobs & Steve Wozniak, but that's another story), and from then on I've composed my writing almost entirely in digital media. In high school, my essays were submitted in blue-black cursive on white lined paper; in college, they were produced on a dot matrix printer that, while painfully slow by modern standards, nevertheless allowed the use of "advanced" features such as italics.
Ah, italics. (Not to be confused with oblique type - again, another story.) The darling of aspiring and over-enthusiastic writers everywhere, italics are used for a whole host of purposes - for emphasis, to indicate foreign-language words, for titles of book-length materials and plays, and to indicate conventions unique to a specific piece of literature. For example, I use italics to indicate interior (non-spoken) dialog, either telepathic between characters, in which case I include quotation marks, or internal prayer/communion with the divine, in which case I leave off the quotation marks.
