65f76581 | 55 | |
787e24c3 KS |
56 | With the default setting, an ordinary Mouse-1 click on a link |
57 | performs the same action as Mouse-2 on that link, while a longer | |
97b1270c | 58 | Mouse-1 click \(hold down the Mouse-1 button for more than 450 |
787e24c3 | 59 | milliseconds) performs the original Mouse-1 binding \(which |
65f76581 KS |
60 | typically sets point where you click the mouse). |
61 | ||
62 | If value is an integer, the time elapsed between pressing and | |
63 | releasing the mouse button determines whether to follow the link | |
787e24c3 | 64 | or perform the normal Mouse-1 action (typically set point). |
22bcf204 | 65 | The absolute numeric value specifies the maximum duration of a |
65f76581 KS |
66 | \"short click\" in milliseconds. A positive value means that a |
67 | short click follows the link, and a longer click performs the | |
1d68acd3 | 68 | normal action. A negative value gives the opposite behavior. |
65f76581 KS |
69 | |
70 | If value is `double', a double click follows the link. | |
71 | ||
787e24c3 | 72 | Otherwise, a single Mouse-1 click unconditionally follows the link. |
65f76581 KS |
73 | |
74 | Note that dragging the mouse never follows the link. | |
75 | ||
76 | This feature only works in modes that specifically identify | |
77 | clickable text as links, so it may not work with some external | |
78 | packages. See `mouse-on-link-p' for details." | |
