-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.
