Thanks. This does not seems to solve it though still.

if i have

(local-set-key (kbd "<C-tab>") (or (key-binding (kbd "<M-tab>"))
                                (key-binding (kbd "M-TAB"))))

then the key is changed for local buffer. If i use global-set-key,
then it's wrong because a specifical completion command name is used
for all. e.g. I get ispell-complete-word for all.

just to make message more clear and independent of the thread, what i
wanted is to set Ctrl+Tab for command completion that works in all
major modes, and avoding adding a custome hook to each and every mode.

Right now i adopted this implementation.

; keyword completion, because Alt+Tab is used by OS
(global-set-key (kbd "M-t") 'call-command-completion)

(defun call-keyword-completion ()
  "Call the function with keyboard shortcut M-TAB."
  (interactive)
  (call-interactively (key-binding (kbd "M-TAB")))
)
