your code mod the global syntax table. you want to mode the syntax
table for that mode. It works when u call manually because when u are
in that mode, it mods that mod's syntax table.

hook is a good solution.
e.g.

(add-hook 'w3m-mode-hook
 (lambda ()
  (define-key w3m-mode-map (kbd "<up>") 'previous-line) ; was w3m-
previous-anchor. Use Shift+Tab.
  (define-key w3m-mode-map (kbd "<down>") 'next-line) ; was w3m-next-
anchor. Use Tab.
  (define-key w3m-mode-map (kbd "<left>") 'backward-char) ; was w3m-
view-previous-page. Use B.
  (define-key w3m-mode-map (kbd "<right>") 'forward-char) ; was w3m-
view-this-url. Use Enter.
))

you want to find the syntax table name for that mode to modify.
