Please refer to the following post

One last question.
Where would I put:
target=”_blank”
So that the post format links in the sidebar widgets open in a new window?
Possible?

if($format == 'link')
                                           {
                                                $current_post = array();
                                                $current_post['content'] = get_the_content();
                                                $current_post['title'] =  get_the_title();
                                                
                                                if(function_exists('avia_link_content_filter'))
                                                {
                                                    $current_post = avia_link_content_filter($current_post);
                                                }
                        
                                                $link = $current_post['url'];
                                            }
