GNU Emacs Lisp Reference Manual
The following is a list of hook variables that let you provide functions to be called from within Emacs on suitable occasions.
Most of these variables have names ending with `-hook'. They are normal hooks, run by means of run-hooks. The value of such a hook is a list of functions. The recommended way to put a new function on such a hook is to call add-hook. See Hooks, for more information about using hooks.
The variables whose names end in `-function' have single functions as their values. Usually there is a specific reason why the variable is not a normal hook, such as the need to pass arguments to the function. (In older Emacs versions, some of these variables had names ending in `-hook' even though they were not normal hooks.)
The variables whose names end in `-hooks' or `-functions' have lists of functions as their values, but these functions are called in a special way (they are passed arguments, or else their values are used).
