The following is a list of hook variables which let you provide functions to be called from within Emacs on suitable occasions.
Most of these variables have names ending with `-hook' are
normal hooks, that are run with 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 section 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 an argument 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' 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).
