 * Ok, I think is resolved for me… I have the $categories_events variable to control
   some things in the template.
 *     ```
       global $EM_Category;
       $arrCategory = get_terms(EM_TAXONOMY_CATEGORY,array('parent'=>0,'hide_empty'=>0) );
       foreach($arrCategory as $arrterm) {
       	$child = get_term_children($arrterm->term_id,EM_TAXONOMY_CATEGORY);
       	foreach($child as $term_child_id) {
       		$term_child = get_term_by('id',$term_child_id,EM_TAXONOMY_CATEGORY);
       		if ( $term_child->name == $EM_Category->name ){
       			$categories_events = $arrterm->slug;					}
       }
       }//fi foreach
       ```

 * For me is working another way without hacking the core: Duplicating, renaming
   and hacking the functions involved to **functions.php** from your template.
 * Only need to insert “_2” to each function & the hack suggest by _vtxyzzy_ in 
   the “get_adjacent_post” function (our get_adjacent_post_2).

 * And the call in the template
 *     ```
       <div class="alignleft"><?php previous_post_link_2('%link', '<', TRUE,'3,10') ?></div>
       <div class="alignright"><?php next_post_link_2('%link', '>', TRUE,'3,10'); ?></div>
       ```
