Once you enable your widget to catch keyboard events with
Gtk::Widget::add_events() and you have connected your widget to the
Gtk::Widget::signal_key_press_event().  Your handler can see which key
has been pressed by using the GdkEventKey[1] structure in your handler.

Remember, your handler should return false if you want the rest of your
widgets to react the the key presses also (see
http://www.gtkmm.org/docs/gtkmm-2.4/docs/tutorial/html/sec-xeventsignals.html).
