  35 ;; Functions for manipulating via the mouse and mouse-map definitions
  36 ;; for accessing them.  Also definitions of mouse menus.
  37 ;; This file you should freely modify to reflect you personal tastes.
  38 ;;
  39 ;; First half of file defines functions to implement mouse commands,
  40 ;; Don't delete any of those, just add what ever else you need.
  41 ;; Second half of file defines mouse bindings, do whatever you want there.
  42
  43 ;;
  44 ;;         Mouse Functions.
  45 ;;
  46 ;; These functions follow the sun-mouse-handler convention of being called
  47 ;; with three arguments: (window x-pos y-pos)
  48 ;; This makes it easy for a mouse executed command to know where the mouse is.
  49 ;; Use the macro "eval-in-window" to execute a function
  50 ;; in a temporarily selected window.
  51 ;;
  52 ;; If you have a function that must be called with other arguments
  53 ;; bind the mouse button to an s-exp that contains the necessary parameters.
  54 ;; See "minibuffer" bindings for examples.

 497 ;;;           Global Mouse Bindings.
 498 ;;;
 499 ;;; There is some sense to this mouse binding madness:
 500 ;;; LEFT and RIGHT scrolls are inverses.
 501 ;;; SHIFT makes an opposite meaning in the scroll bar.
 502 ;;; SHIFT is an alternative to DOUBLE (but double chords do not exist).
 503 ;;; META makes the scrollbar functions work in the text region.
 504 ;;; MIDDLE operates the mark
 505 ;;; LEFT operates at point
 506
 507 ;;; META commands are generally non-destructive,
 508 ;;; SHIFT is a little more dangerous.
 509 ;;; CONTROL is for the really complicated ones.
 510
 511 ;;; CONTROL-META-SHIFT-RIGHT gives help on that region.
