Microsoft has already made the option available for YOU to create your own STYLE and call it anything you want to. See: http://www.shaunakelly.com/topic/word/styles. YOU can create the style called "TYPEWRITER" and format the tabs, font, spacing and make it as cooperative as you like. (I would never do this myself).

Having said that, not knowing your comfort level with Word nor the business that you use it, becoming "real familiar" with the above link ref styles could help you tremendously.
