Item in the formatting dropdown for preformatted text

"Pre-formatted" is the formal term for this kind of formatting - see this page from W3C from 1997; roughly, it means "mono-spaced font, white space is listened to". The text retains all its other styling, though, and if you change it to a format that is more regular (like paragraph or eventually blockquote) you should still get all the styling retained as before.
