  35 ;;; for accessing them.  Also definitions of mouse menus.
  36 ;;; This file you should freely modify to reflect you personal tastes.
  37 ;;;
  38 ;;; First half of file defines functions to implement mouse commands,
  39 ;;; Don't delete any of those, just add what ever else you need.
  40 ;;; Second half of file defines mouse bindings, do whatever you want there.

  43 ;;;         Mouse Functions.
  44 ;;;
  45 ;;; These functions follow the sun-mouse-handler convention of being called
  46 ;;; with three arguments: (window x-pos y-pos)
  47 ;;; This makes it easy for a mouse executed command to know where the mouse is.
  48 ;;; Use the macro "eval-in-window" to execute a function
  49 ;;; in a temporarily selected window.
  50 ;;;
  51 ;;; If you have a function that must be called with other arguments
  52 ;;; bind the mouse button to an s-exp that contains the necessary parameters.
  53 ;;; See "minibuffer" bindings for examples.

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