flipper
n.— «So CNN last week replaced the crawl with what it calls the flipper—a move, Mr. Feder said, that was designed to impart information but that “doesn’t give viewers a headache.” Usually, the flipper is a line of text at the bottom of the screen that is tied to the story on air. Less frequently, the flipper shows headlines of other stories but without the distraction of the scroll.» —“The Flipper Challenges the Crawl” by Brian Stelter New York Times Dec. 21, 2008.
