Thanks David, that's slightly more convenient than entering a terminal
emulator *and then* entering "su..." --- but I mean something
different.  I'd like to run root commands straight from an editor
window, for example Dired.  Deleting files is fine, I just do dired
with "/su::<directory>" and then run the regular dired commands.
Sometimes I want to do a command that requires root privileges.
