OK, figured it out.  Added this to the top of my script:

from gi.repository import Gtk, Gdk


Have this in my class init:


self.window.connect("key_press_event", self.combo_catcher)


And then have my code set up like this:

def combo_catcher(self, widget, event):

keyname = Gdk.keyval_name(event.keyval)

ctrl = event.state & Gdk.ModifierType.CONTROL_MASK

if ctrl:

print 'Control was pushed with ', keyname


got most of that from a stackoverflow post here:

I can get to sleep now.
