   9 The following is a list of hook variables that let you provide
  10 functions to be called from within Emacs on suitable occasions.
  11
  12 Most of these variables have names ending with @samp{-hook}.  They are
  13 @dfn{normal hooks}, run by means of @code{run-hooks}.  The value of such
  14 a hook is a list of functions; the functions are called with no
  15 arguments and their values are completely ignored.  The recommended way
  16 to put a new function on such a hook is to call @code{add-hook}.
  17 @xref{Hooks}, for more information about using hooks.
  18
  19 Every major mode defines a mode hook named
  20 @samp{@var{modename}-mode-hook}.  The major mode command runs this
  21 normal hook with @code{run-mode-hooks} as the very last thing it does.
  22 @xref{Mode Hooks}.  Most minor modes have mode hooks too.  Mode hooks
  23 are omitted in the list below.
  24
  25 The variables whose names end in @samp{-hooks} or @samp{-functions} are
  26 usually @dfn{abnormal hooks}; their values are lists of functions, but
  27 these functions are called in a special way (they are passed arguments,
  28 or their values are used).  A few of these variables are actually normal
  29 hooks which were named before we established the convention that normal
  30 hooks' names should end in @samp{-hook}.
  31
  32 The variables whose names end in @samp{-function} have single functions
  33 as their values.  (In older Emacs versions, some of these variables had
  34 names ending in @samp{-hook} even though they were not normal hooks;
  35 however, we have renamed all of those.)
  36
  37 @c We need to xref to where each hook is documented or else document
  38 @c it here.
