  72 TOGGLE is a symbol which is used as the variable which toggle the minor mode,
  73 NAME is the name that should appear in the modeline (it should be a string
  74 beginning with a space), KEYMAP is a keymap to make active when the minor
  75 mode is active, and AFTER is the toggling symbol used for another minor
  76 mode.  If AFTER is non-nil, then it is used to position the new mode in the
  77 minor-mode alists.  TOGGLE-FUN specifies an interactive function that
  78 is called to toggle the mode on and off; this affects what appens when
  79 button2 is pressed on the mode, and when button3 is pressed somewhere
  80 in the list of modes.  If TOGGLE-FUN is nil and TOGGLE names an
  81 interactive function, TOGGLE is used as the toggle function.
