Launching Nautilus as su?

["Giorgos" <giorgos67 gmail com>]

Hi! :-)

Does somebody know, how can I launch nautilus, as su?
I'm launching nautilus, as a normal user, and not surprisingly, copy-pasting 
is greyed out at many folders.
OK, I'm always able to work with bash. I just wanted to avoid the so much 
keyboarding . :-)
(I have installed here the latest stable version of opensuse (with gnome 
desktop), but I couldn't found this option).

THANKS!!!
Giorgos. :-)
