Here is an update to my original question.
I would like to show the News Manager content on a Page Template other than single.php, which seems to be the default.
AND
On that page I would like to present al list of all the News entries similar to blog posts. Do you have a widget or shortcode for displaying x number of News posts?
Something similar to this but for News Manager posts:
$get_posts = get_posts(array('numberposts' => -1));
foreach($get_posts as $sidebar_post) {
echo "<li><a>ID) .'">". $sidebar_post->post_title ."</a></li>";
}
