+@section Mouse Avoidance
+
+Mouse Avoidance mode keeps the window system mouse pointer away from
+point to avoid obscuring text. Whenever the mouse is moved, the frame
+is also raised. To use it, customize the option
+@code{mouse-avoidance-mode}. You can set this to various values to move
+the mouse in several ways:
+
+@table @code
+@item banish
+Move the mouse to the upper-right corner on any keypress;
+@item exile
+Move the mouse to the corner only if the cursor gets too close,
+and allow it to return once the cursor is out of the way;
+@item jump
+If the cursor gets too close to the mouse, displace the mouse
+a random distance & direction;
+@item animate
+As @code{jump}, but shows steps along the way for illusion of motion;
+@item cat-and-mouse
+The same as @code{animate};
+@item proteus
+As @code{animate}, but changes the shape of the mouse pointer too.
+@end table
+
+You can also use the command @kbd{M-x mouse-avoidance-mode} to turn on
+the mode.
