  10 @cindex hook variables, list of
  11
  12 The following is a list of hook variables that let you provide
  13 functions to be called from within Emacs on suitable occasions.
  14
  15 Most of these variables have names ending with @samp{-hook}.  They are
  16 @dfn{normal hooks}, run by means of @code{run-hooks}.  The value of such
  17 a hook is a list of functions; the functions are called with no
  18 arguments and their values are completely ignored.  The recommended way
  19 to put a new function on such a hook is to call @code{add-hook}.
  20 @xref{Hooks}, for more information about using hooks.
  21
  22 Every major mode defines a mode hook named
  23 @samp{@var{modename}-mode-hook}.  The major mode command runs this
  24 normal hook with @code{run-mode-hooks} as the very last thing it does.
  25 @xref{Mode Hooks}.  Most minor modes have mode hooks too.  Mode hooks
  26 are omitted in the list below.
  27
  28 The variables whose names end in @samp{-hooks} or @samp{-functions} are
  29 usually @dfn{abnormal hooks}; their values are lists of functions, but
  30 these functions are called in a special way (they are passed arguments,
  31 or their values are used). The variables whose names end in
  32 @samp{-function} have single functions as their values.
  33
  34 A special feature allows you to specify expressions to evaluate if and
  35 when a file is loaded (@pxref{Hooks for Loading}).  That feature is
  36 not exactly a hook, but does a similar job.
  37
  38 @c We need to xref to where each hook is documented or else document
  39 @c it here.
