Standard Hooks

The following is a list of some 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 functions are called with no arguments and their values are completely ignored. The recommended way to put a new function on such a hook is to call add-hook. Hooks, for more information about using hooks. The variables whose names end in -functions are usually abnormal hooks (some old code may also use the deprecated -hooks suffix). Their values are lists of functions, but these functions are called in a special way: they are either passed arguments, or their return values are used in some way. The variables whose names end in -function have single functions as their values. This is not an exhaustive list, it only covers the more general hooks. For example, every major mode defines a hook named MODENAME-mode-hook. The major mode command runs this normal hook with run-mode-hooks as the very last thing it does. Mode Hooks. Most minor modes have mode hooks too. A special feature allows you to specify expressions to evaluate if and when a file is loaded (Hooks for Loading). That feature is not exactly a hook, but does a similar job.
