I found this can be changed via dconf, for those of you (like me) who don't use Gnome or Unity and can't access this hidden menu

Due to a faulty upgrade, my Ubuntu 13.04 desktop turned out to be missing the indicator-appmenu (and dependencies). And without those, there was no global menu. That wasn't a problem for me, until I found out that I couldn't put the gnome-calculator back into PROGRAMMING mode because it had no menu to do so [2]. I tried to hack around a bit in the code, but I didn't get very far. See patch attempt in [2]. Kind regards, Walter Doekes OSSO B.V.
