Gnome = gtksudo, KDE = ???

[Tipton, Timothy]

I am trying to figure out what the KDE equivalent is to gtksudo, can you
guys throw me a bone?

What I'm trying to do is to edit a conf file to add in USB support for
virtualbox ose - I found a tutorial that says to add in a certain line
to my fstab so that it will pass along my usb stuff to the vm. (can you
tell I'm waaaay out of my league here? ;O )

Also, what is the kde favorite for editing files? Vim or something like
that? So the line would be "qtsudo (or whatever it is) vim
/ect/blah/foo.conf" ?

Thanks for the help!
Tim
