46 addition to mouse drags."
52 "Non-nil means that clicking Mouse-1 on a link follows the link.
54 With the default setting, an ordinary Mouse-1 click on a link
55 performs the same action as Mouse-2 on that link, while a longer
56 Mouse-1 click \(hold down the Mouse-1 button for more than 450
57 milliseconds) performs the original Mouse-1 binding \(which
58 typically sets point where you click the mouse).
60 If value is an integer, the time elapsed between pressing and
61 releasing the mouse button determines whether to follow the link
62 or perform the normal Mouse-1 action (typically set point).
63 The absolute numeric value specifies the maximum duration of a
65 short click follows the link, and a longer click performs the
66 normal action. A negative value gives the opposite behavior.
68 If value is `double', a double click follows the link.
70 Otherwise, a single Mouse-1 click unconditionally follows the link.
72 Note that dragging the mouse never follows the link.
74 This feature only works in modes that specifically identify
75 clickable text as links, so it may not work with some external
76 packages. See `mouse-on-link-p' for details."
85 "If non-nil, a Mouse-1 click also follows links in non-selected windows.
87 If nil, a Mouse-1 click on a link in a non-selected window performs
88 the normal mouse-1 binding, typically selects the window and sets
89 point at the click position."

742 is a non-nil `mouse-face' property at POS. Return t in this case.
744 - If the value is a function, FUNC, POS is inside a link if
