24 ;;; Commentary:
26 ;; This package provides various useful commands (including help
27 ;; system access) through the mouse. All this code assumes that mouse
28 ;; interpretation has been abstracted into Emacs input events.
29 ;;
30 ;; The code is rather X-dependent.

34 ;;; Utility functions.

40 "If non-nil, mouse yank commands yank at point instead of at click."
45 "If non-nil, mouse drag copies region to kill-ring."
51 "Non-nil means that clicking Mouse-1 on a link follows the link.
53 With the default setting, an ordinary Mouse-1 click on a link
54 performs the same action as Mouse-2 on that link, while a longer
55 Mouse-1 click \(hold down the Mouse-1 button for more than 450
56 milliseconds) performs the original Mouse-1 binding \(which
57 typically sets point where you click the mouse).
59 If value is an integer, the time elapsed between pressing and
60 releasing the mouse button determines whether to follow the link
61 or perform the normal Mouse-1 action (typically set point).
62 The absolute numeric value specifices the maximum duration of a
64 short click follows the link, and a longer click performs the
65 normal action. A negative value gives the opposite behavior.
67 If value is `double', a double click follows the link.
69 Otherwise, a single Mouse-1 click unconditionally follows the link.
71 Note that dragging the mouse never follows the link.
73 This feature only works in modes that specifically identify
74 clickable text as links, so it may not work with some external
75 packages. See `mouse-on-link-p' for details."
84 "If non-nil, a Mouse-1 click also follows links in non-selected windows.
86 If nil, a Mouse-1 click on a link in a non-selected window performs
87 the normal mouse-1 binding, typically selects the window and sets
88 point at the click position."

840 for the `follow-link' event, the binding of that event determines
841 what to do.

845 - If the value is `mouse-face', POS is inside a link if there
846 is a non-nil `mouse-face' property at POS. Return t in this case.
848 - If the value is a function, FUNC, POS is inside a link if
849 the call \(FUNC POS) returns non-nil. Return the return value
850 from that call. Arg is \(posn-point POS) if POS is a mouse event.
852 - Otherwise, return the value itself.

856 - If it is a string, the mouse-1 event is translated into the
857 first character of the string, i.e. the action of the mouse-1
858 click is the local or global binding of that character.

861 first element of that vector, i.e. the action of the mouse-1
