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