address@hidden indicate-buffer-boundaries
+  On a graphical display, Emacs can indicate the buffer boundaries in
+the fringes.  It indicates the first line and the last line with
+angle images in the fringes.  This can be combined with up and down
+arrow images which say whether it is possible to scroll the window up
+and down.
+
+  The buffer-local variable @code{indicate-buffer-boundaries} controls
+how the buffer boundaries and window scrolling is indicated in the
+fringes.  If the value is @code{left} or @code{right}, both angle and
+arrow bitmaps are displayed in the left or right fringe, respectively.
+
+  If value is an alist, each element @code{(@var{indicator} .
address@hidden)} specifies the position of one of the indicators.
+The @var{indicator} must be one of @code{top}, @code{bottom},
address@hidden, @code{down}, or @code{t} which specifies the default
+position for the indicators not present in the alist.
+The @var{position} is one of @code{left}, @code{right}, or @code{nil}
+which specifies not to show this indicator.
+
+  For example, @code{((top . left) (t . right))} places the top angle
+bitmap in left fringe, the bottom angle bitmap in right fringe, and
+both arrow bitmaps in right fringe.  To show just the angle bitmaps in
+the left fringe, but no arrow bitmaps, use @code{((top .  left)
+(bottom . left))}.
