At the risk of stating the obvious, you need to put that in your ~/.emacs
(~/.xemacs? or wasn't it in some subdir with xemacs? I don't know...) and then
restart xemacs to make sure it takes effect.

a hook is simply a list of functions that are run when a certain mode is

Emacs comes with an introduction to Elisp and the full documentation to Elisp.
Just start info mode (C-h i) and search for 'Emacs Lisp Intro' and 'Elisp'.

Which is not going to work, because only the first matching mode in
auto-mode-alist is activated. That's why auto-mode-alist should only be used for
major modes, not for minor modes. Minor modes (like flyspell-mode) should be
turned on via mode hooks.

That's not going to work because of the way auto-mode-alist works. It requires
exactly one mode function in each option, it does not handle more. (Essentially
because auto-mode-alist is for setting the major mode of a buffer and a buffer
can only have one major mode.)

The correct way for turning it on for specific modes only is through hooks.
AFAICT, the line above should really work. I have no idea why it doesn't in your
