Just because I have seen it for the first time: If you press <shift> in the Nomad GUI, it will show you the keyboard shortcuts for the various menu items. I just wasn't able to screenshot it.
"gj" brings you to the Job menu. "gv" to the Variables. You can go through the lists with <shift>,<0>,<1> (press one after the other). "u" brings you up one menu.
Very nice.
