binding key for tags command

[Seong-Kook Shin]

Hi,

I use tag command heavily, espcially "M-.", "C-u M-.", and "C-u - M-.".
And I want to change the 2nd and the 3rd to other key combination since
it's too time consuming to press those keys.

But the problem is that there is no specific funtion matching
"C-u M-." and "C-u - M-.". I realize those commands actually pass
some argument to find-tag lisp function, but I'm not familar to lisp.

All I want is:

  - I want to use "M-[" for "C-u M-.", and
  - I want to use "M-]" for "C-u - M-."

Of course, I tried to use global-set-key function but failed since those
commands are not real function.

Is there anyone who can enlighten me? ;-)
