If a customization item has a type such as @code{hook} or
@code{alist}, which supports @code{:options}, you can add additional
values to the list from outside the @code{defcustom} declaration by
-calling @code{custom-add-option}. For example, if you define a
+calling @code{custom-add-frequent-value}. For example, if you define a
function @code{my-lisp-mode-initialization} intended to be called from
@code{emacs-lisp-mode-hook}, you might want to add that to the list of
reasonable values for @code{emacs-lisp-mode-hook}, but not by editing
its definition. You can do it thus:
@example
-(custom-add-option 'emacs-lisp-mode-hook
- 'my-lisp-mode-initialization)
+(custom-add-frequent-value 'emacs-lisp-mode-hook
+ 'my-lisp-mode-initialization)
@end example
-@defun custom-add-option symbol value
+@defun custom-add-frequent-value symbol value
For the customization option @var{symbol}, add @var{value} to the
list of reasonable values.
