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