Bootstrap: Carousel with keyboard controls

Has anyone been able to implement Twitter Bootstrap carousel with keyboard controls? I know this is going to be implement in the next release, but for now I was wondering if any of you has been able to make it work.

Here’s my current code:

<script type="text/javascript">

  jQuery(document).keypress(function(event) {

  if (event.keyCode === RIGHT_ARROW) {
  $('a.carousel-control.right').trigger('click');

  }

  if (event.keyCode === LEFT_ARROW) {

  $('a.carousel-control.left').trigger('click');

  }

  });

</script>

But I’m not getting anywhere with this. Any ideas?

Edit: Here’s the WordPress code I am running…

                        <?php if (have_posts()) : while (have_posts()) : the_post(); ?>

                        <article id="post-<?php the_ID(); ?>" <?php post_class('clearfix'); ?> role="article" itemscope itemtype="http://schema.org/BlogPosting">


                            <?php if ( $post->post_type == 'portfolios' && $post->post_status == 'publish' ) {
                            $attachments = get_posts( array(

                            'post_type' => 'attachment',
                            'posts_per_page' => -1,
                            'post_parent' => $post->ID,
                            'exclude' => get_post_thumbnail_id(),
                            'orderby' => 'menu_order',
                            'order' => 'ASC'    
                                ) );

                            ?>

                            <?php if ( $attachments ) {  
                            $the_rest = array_slice($attachments, 0, 100);
                            ?>      

                            <div id="carousel-<?php the_ID(); ?>" class="featured-carousel carousel slide carousel-fade">

                                <div class="carousel-inner">

                                    foreach( $the_rest as $attachment) :
                                    $image = wp_get_attachment_image_src( $attachment->ID, 'orion-thumb-900', false );
                                    $post_num++;
                                    ?>
