65f76581 | 56 | |
787e24c3 KS |
57 | With the default setting, an ordinary Mouse-1 click on a link |
58 | performs the same action as Mouse-2 on that link, while a longer | |
97b1270c | 59 | Mouse-1 click \(hold down the Mouse-1 button for more than 450 |
787e24c3 | 60 | milliseconds) performs the original Mouse-1 binding \(which |
65f76581 KS |
61 | typically sets point where you click the mouse). |
62 | ||
63 | If value is an integer, the time elapsed between pressing and | |
64 | releasing the mouse button determines whether to follow the link | |
787e24c3 | 65 | or perform the normal Mouse-1 action (typically set point). |
65f76581 KS |
66 | The absolute numeric value specifices the maximum duration of a |
67 | \"short click\" in milliseconds. A positive value means that a | |
68 | short click follows the link, and a longer click performs the | |
1d68acd3 | 69 | normal action. A negative value gives the opposite behavior. |
65f76581 KS |
70 | |
71 | If value is `double', a double click follows the link. | |
72 | ||
787e24c3 | 73 | Otherwise, a single Mouse-1 click unconditionally follows the link. |
65f76581 KS |
74 | |
75 | Note that dragging the mouse never follows the link. | |
76 | ||
77 | This feature only works in modes that specifically identify | |
78 | clickable text as links, so it may not work with some external | |
79 | packages. See `mouse-on-link-p' for details." | |
