GtkEntry doesn't using GtkBindings right now, so it never
calls gtk_bindings_activate() (this will be fixed in GTK+-2.0)

A workaround hack you can do if it is your own app is:

======
static gboolean
editable_key_press_cb (GtkWidget *widget, GdkEventKey *event)
{
  if (gtk_bindings_activate (GTK_OBJECT (widget), event->keyval, event->state))
    {
      gtk_signal_emit_stop_by_name (GTK_OBJECT (widget), "key_press_event");
      return TRUE;
    }
  else
    return FALSE;
}

[...]

  gtk_signal_connect (GTK_OBJECT (editable), "key_press_event",
		      GTK_SIGNAL_FUNC (editable_key_press_cb), NULL);
======
