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