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 | |
97b1270c | 57 | Mouse-1 click \(hold down the Mouse-1 button for more than 450 |
787e24c3 | 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 | |
1d68acd3 | 67 | normal action. A negative value gives the opposite behavior. |
65f76581 KS |
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." | |

829 | what to do. | |
65f76581 | 830 | |

831 | The resulting value determine whether POS is inside a link: |

835 | ||
b41a4019 | 836 | - If the value is a function, FUNC, POS is inside a link if |
65f76581 | 837 | the call \(FUNC POS) returns non-nil. Return the return value |
23eb76c4 | 838 | from that call. Arg is \(posn-point POS) if POS is a mouse event. |

65f76581 KS |

842 | The return value is interpreted as follows: | |

844 | - If it is a string, the mouse-1 event is translated into the | |
845 | first character of the string, i.e. the action of the mouse-1 | |
846 | click is the local or global binding of that character. | |
