26 ;;; Commentary:
28 ;; This package provides various useful commands (including help
29 ;; system access) through the mouse. All this code assumes that mouse
30 ;; interpretation has been abstracted into Emacs input events.
31 ;;
32 ;; The code is rather X-dependent.
34 ;;; Code:
36 ;;; Utility functions.
38 ;; Indent track-mouse like progn.
42 "*If non-nil, mouse yank commands yank at point instead of at click."
47 "*If non-nil, mouse drag copies region to kill-ring."
53 "Non-nil means that clicking Mouse-1 on a link follows the link.
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 450
58 milliseconds) performs the original Mouse-1 binding \(which
59 typically sets point where you click the mouse).
61 If value is an integer, the time elapsed between pressing and
62 releasing the mouse button determines whether to follow the link
63 or perform the normal Mouse-1 action (typically set point).
64 The absolute numeric value specifices the maximum duration of a
66 short click follows the link, and a longer click performs the
67 normal action. A negative value gives the opposite behavior.
69 If value is `double', a double click follows the link.
71 Otherwise, a single Mouse-1 click unconditionally follows the link.
73 Note that dragging the mouse never follows the link.
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."
86 "*If non-nil, a Mouse-1 click also follows links in non-selected windows.
88 If nil, a Mouse-1 click on a link in a non-selected window performs
89 the normal mouse-1 binding, typically selects the window and sets
90 point at the click position."

821 - If the character at POS has a non-nil `follow-link' text or
822 overlay property, the value of that property determines what to do.
824 - If there is a local key-binding or a keybinding at position POS
825 for the `follow-link' event, the binding of that event determines
826 what to do.
828 The resulting value determine whether POS is inside a link:
830 - If the value is `mouse-face', POS is inside a link if there
831 is a non-nil `mouse-face' property at POS. Return t in this case.
833 - If the value is a function, FUNC, POS is inside a link if
834 the call \(FUNC POS) returns non-nil. Return the return value
835 from that call. Arg is \(posn-point POS) if POS is a mouse event.
837 - Otherwise, return the value itself.
839 The return value is interpreted as follows:
841 - If it is a string, the mouse-1 event is translated into the
842 first character of the string, i.e. the action of the mouse-1
843 click is the local or global binding of that character.
845 - If it is a vector, the mouse-1 event is translated into the
846 first element of that vector, i.e. the action of the mouse-1
847 click is the local or global binding of that event.
