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

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