function be_follow_icons($menu, $args) {
	$args = (array)$args;
	if ( 'primary' !== $args['theme_location']  )
		return $menu;
	$follow = '<li id="follow">Follow: <a rel="nofollow" class="rss" href="'.get_bloginfo('rss_url').'"><img src="'.get_bloginfo('stylesheet_directory').'/images/feed.png" /></a> <a rel="nofollow" class="twitter" href="'.esc_url( 'http://twitter.com/' .genesis_get_option('nav_extras_twitter_id') ).'"><img src="'.get_bloginfo('stylesheet_directory').'/images/twitter.png" /></a></li>';
	return $menu . $follow;
}

i would like to add the icons to the beginning of a navigation I call 'top navigation'. would I be able to change 'primary' to the name of the menu?
