Thanks for your reply.

I do not want to interactive call a function but call it like pressing a key.
for example, press tab in help-mode will cause forward-button function which
has a parameter, however I do not need give it parameter and it get parameter
by itself. 

my aim is to binding a funtion to tab key in every mode: if cursor is at 
the end of word then call M-TAB's function, else call TAB's function.

(defun my-indent-or-complete ()
   "if cursor is at 
   the end of word then call M-TAB's function, else call TAB's function."
  (interactive)
  ;; ^C^t is binding to tab key's function in mode-hook.
  (let ((TAB-func (key-binding "^C^t"))
	(M-TAB-func (key-binding "\M-\t"))
	)
   (if (looking-at "\\>")
          (apply M-TAB-func '())
        (apply TAB-func '())
     ))
  )

my way is only suitable for lisp-indent-line but not forward-button.
