19. Controlling the Display

Since only part of a large buffer fits in the window, Emacs tries to show a part that is likely to be interesting. Display-control commands allow you to specify which part of the text you want to see, and how to display it. Many variables also affect the details of redisplay. Unless otherwise stated, the variables described in this chapter have their effect by customizing redisplay itself; therefore, their values only make a difference at the time of redisplay.
