Using the Slider in the Scroll Bar

  Use the slider in the center of the scroll bar to move quickly
  through text.

  The size and location of the slider indicates your position in
  the text.  A small slider at the top of the scroll bar indicates
  you are at the beginning of a large piece of text.  A large
  slider that fills the scroll bar indicates that you are viewing
  the entire body of the text.

  To move to another portion of the text, press MB1 in the
  slider region, drag the slider to an area representing the
  portion of text to be displayed, and release MB1.  For example,
  to move to the last portion of the text, drag the slider to the
  bottom of the scroll bar and release MB1.
