Python Tkinter Dropdown Menu w/Keyboard Shortcuts

Question

I would like to have a Dropdown Menu in Tkinter, that includes the shortcut key associated with this command. Is this possible?

EDIT: How would I also add the underline under a certain character, to allow for Alt-F-S (File->Save)?

import Tkinter
import sys

class App(Tkinter.Tk):
    def __init__(self):
        Tkinter.Tk.__init__(self)
        menubar = Tkinter.Menu(self)
        fileMenu = Tkinter.Menu(menubar, tearoff=False)
        menubar.add_cascade(label="File",underline=0, menu=fileMenu)
        fileMenu.add_command(label="Exit", underline=1, 
                             command=quit, accelerator="Ctrl+Q")
        self.config(menu=menubar)

        self.bind_all("<Control-q>", self.quit)

    def quit(self, event):
        print "quitting..."
        sys.exit(0)

if __name__ == "__main__":
    app=App()
    app.mainloop()
