787e24c3 | 53 | "Non-nil means that clicking Mouse-1 on a link follows the link. |
65f76581 | 54 | |
787e24c3 KS |
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 350 | |
58 | milliseconds) performs the original Mouse-1 binding \(which | |
65f76581 KS |
59 | typically sets point where you click the mouse). |
60 | ||
61 | If value is an integer, the time elapsed between pressing and | |
62 | releasing the mouse button determines whether to follow the link | |
787e24c3 | 63 | or perform the normal Mouse-1 action (typically set point). |
65f76581 KS |
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 behaviour. | |
68 | ||
69 | If value is `double', a double click follows the link. | |
70 | ||
787e24c3 | 71 | Otherwise, a single Mouse-1 click unconditionally follows the link. |
65f76581 KS |
72 | |
73 | Note that dragging the mouse never follows the link. | |
74 | ||
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." | |

772 | A clickable link is identified by one of the following methods: | |
773 | ||
a0ec7b7f KS |
774 | If the character at POS has a non-nil `follow-link' text or |
775 | overlay property, use the value of that property as action code, | |
776 | or if there is a local key-binding or a keybinding at position | |
777 | POS for the `follow-link' event, use the binding of that event as | |
778 | action code. | |
65f76581 | 779 | |
a0ec7b7f | 780 | The action code is used to determine whether POS is inside a link: |
65f76581 | 781 | |
a0ec7b7f | 782 | - If the action code is `mouse-face', POS is inside a link if there |
65f76581 KS |
783 | is a non-nil `mouse-face' property at POS. Return t in this case. |
784 | ||
a0ec7b7f | 785 | - If the action code is a function, FUNC, POS is inside a link if |
65f76581 KS |
786 | the call \(FUNC POS) returns non-nil. Return the return value |
787 | from that call. | |
788 | ||
a0ec7b7f | 789 | - Otherwise, return the action code itself. |
65f76581 KS |
790 | |
791 | The return value is interpreted as follows: | |
792 | ||
793 | - If it is a string, the mouse-1 event is translated into the | |
794 | first character of the string, i.e. the action of the mouse-1 | |
795 | click is the local or global binding of that character. | |
796 | ||
797 | - If it is a vector, the mouse-1 event is translated into the | |
798 | first element of that vector, i.e. the action of the mouse-1 | |
799 | click is the local or global binding of that event. | |
