-If value is a cons @code{(@var{angles} . @var{arrows})}, @var{angles}
-controls the angle icons, and @var{arrows} controls the arrows.  Both
-@var{angles} and @var{arrows} work according to the table above.
-Thus, @code{(t .  right)} places the top angle icon in the left
-fringe, the bottom angle icon in the right fringe, and both arrows in
-the right fringe.
+Otherwise the value should be an alist that specifies which fringe
+indicators to display and where.  Each element of the alist should
+have the form @code{(@var{indicator} . @var{position})}.  Here,
+@var{indicator} is one of @code{top}, @code{bottom}, @code{up},
+@code{down}, and @code{t} (which covers all the icons not yet
+specified), while @var{position} is one of @code{left}, @code{right}
+and @code{nil}.
+
+For example, @code{((top . left) (t . right))} places the top angle
+bitmap in left fringe, and the bottom angle bitmap as well as both
+arrow bitmaps in right fringe.  To show the angle bitmaps in the left
+fringe, and no arrow bitmaps, use @code{((top .  left) (bottom . left))}.
