The general thing to do is to find the variable that contains the "hooks" that 
are called when caml-mode is entered.  Supposing the variable is called 
caml-mode-hook, you can add to it a function that sets C-[down] to the same 
thing that C-c C-e is set to.  It will look something like

(add-hook 'caml-mode-hook
          (lambda ()
             (local-set-key "C-[down]" 
the-function-that-sends-current-phrase))))

If there are any users of Caml mode on this list, they can give you more a 
specific tip.

But you would be better off reading the Emacs manual chapter on Customizing Key 
Bindings.

Cheers,

be this complicated!
