352 TOGGLE is a symbol whose value as a variable specifies whether the
|
|
|
353 minor mode is active.
|
|
|
354
|
|
|
355 NAME is the name that should appear in the modeline. It should either
|
|
|
356 be a string beginning with a space, or a symbol with a similar string
|
|
|
357 as its value.
|
|
|
358
|
|
|
359 KEYMAP is a keymap to make active when the minor mode is active.
|
|
|
360
|
|
|
361 AFTER is the toggling symbol used for another minor mode. If AFTER is
|
|
|
362 non-nil, then it is used to position the new mode in the minor-mode
|
|
|
363 alists.
|
|
|
364
|
|
|
365 TOGGLE-FUN specifies an interactive function that is called to toggle
|
|
|
366 the mode on and off; this affects what happens when button2 is pressed
|
|
|
367 on the mode, and when button3 is pressed somewhere in the list of
|
|
|
368 modes. If TOGGLE-FUN is nil and TOGGLE names an interactive function,
|
|
|
369 TOGGLE is used as the toggle function.
