way to run application as root in fluxbox menu

[Brian John]

Hello, I want to be able to add k3b to my menu in fluxbox.  However, it
has to be run as root and I'm not sure how to do that.  Is there a way
that I could get k3b to automatically run as root in fluxbox?  It is ok if
I have to enter my root password every time that I run it.

Thanks
