How-to

This shows how to modify the output inside the internal link checker meta box (in case you want to extend its functionality):

function modify_check_link_meta_box_content( $result, $links )
{
    global $post;

    // Uncomment the follwing line to see what the $links array contains
    // The links array contains all posts (and their respective data) that link to the current post
    /*
    echo '';
        print_r( $links );
    echo '';
     */

    // Now handle the result:
    foreach ( $result as $link )
    {
        // do stuff
    }

    return $result;
}
add_filter( 'internal_links_meta_box', 'modify_check_link_meta_box_content', 10, 2 );
