This doesn't work (at least on my emacs on my system).  I get an error
which says

  Wrong type argument: commandp, (lambda nil (find-tag nil t))

The thing that does work here is

  (defun my-find-tag-next ()
    (interactive)
    (find-tag nil t))

  (define-key sun-raw-map "212z" 'my-find-tag-next)

This is because the third argument to define-key must be nil, a command,
a string, a keymap, or a list consisting of elements of the form 
(keymap . char).
