+
+With the default setting, an ordinary Mouse-1 click on a link
+performs the same action as Mouse-2 on that link, while a longer
+Mouse-1 click \(hold down the Mouse-1 button for more than 450
+milliseconds) performs the original Mouse-1 binding \(which
+typically sets point where you click the mouse).
+
+If value is an integer, the time elapsed between pressing and
+releasing the mouse button determines whether to follow the link
+or perform the normal Mouse-1 action (typically set point).
+The absolute numeric value specifices the maximum duration of a
+\"short click\" in milliseconds. A positive value means that a
+short click follows the link, and a longer click performs the
+normal action. A negative value gives the opposite behavior.
+
+If value is `double', a double click follows the link.
+
+Otherwise, a single Mouse-1 click unconditionally follows the link.
+
+Note that dragging the mouse never follows the link.
+
+This feature only works in modes that specifically identify
+clickable text as links, so it may not work with some external
+packages. See `mouse-on-link-p' for details."

+click is the local or global binding of that character.

+- If it is a vector, the mouse-1 event is translated into the
