To capture any key event you add a signal handler to "key_press_event".
Then you just look at the key-value in the event structure. I've
attached a small example of capturing both key-events and mouse-events.

static void
key_event (GtkWidget * dummy, GdkEvent * event)

  g_print ("key_event\n");
}

static void
button_event (GtkWidget * dummy, GdkEvent * event)
{
  g_print ("button_event\n");
}

main (int argc, char *argv[])

  GtkWidget *win;

  gtk_init (&argc, &argv);

  gtk_widget_show_all (win);

  gtk_main ();
