Ah yes, that's a little different. I don't think Tkinter supports
doing that directly but it is possible to do. The trick is to have
your main window accept the key event and act on it.

Here's an example of that. There's more detail in Fredrik Lundh's
excellent An Introduction to Tkinter. This page (wrapped for line
length) may be a good start:

    return "break" # No further processing of this keystroke

  def quitKey(self,event):
    self.quit()

  def doSomething(self):
    print "foo"
    return None

  def quit(self):
    sys.exit(0)

  mainWin(root)
  root.mainloop()

if __name__=="__main__":
  main()
