Okay, that seems reasonable. I suppose that the slot gets attached by
fetching the Gtk::Action::signal_activate object, but how does one
specify the actual accelerator (for purposes of argument, suppose it's
the Escape key) that should be used to activate the action? I don't
see any obvious function on the Action class which attaches an
accelerator.

Suppose we've got the following already:

 Gtk::Window w;
 Glib::RefPtr<Gtk::Action> refAction = Gtk::Action::create ();
 Glib::RefPtr<Gtk::AccelGroup> refGroup = Gtk::AccelGroup::create ();

 w.add_accel_group (w);
 refAction.signal_activate ().connect ( ... );
 // what next?


This question seems to be straying into just questions about Gtk+ API;
feel free to direct me to gtk-list instead.
