No, they are the most primitive things in general, though some could be
written (via scheme) as a sequence of others. (I am thinking of things
like add an f-sharp major keysignature command, which presumably could
be done some other way ... perhaps not easily ... but then, who actually
wants such a command?)
One difference (IIRC) is that they use gtk_action_group_add_actions to
add the commands specified via an array of GtkActionEntry structures.
