[jQuery] code optimizing

[jQuery] code optimizing

hei everybody,
i got this little snipped and i am wondering about how to make it more efficient:
$('#respond').show();
    $('#formComment').hide().addClass('javaCommentForm');
    $("#respond").click(function(){
        $('.storyBox').animate({"opacity": "0.4"});
        $('#formComment').slideToggle();
        $(this).css('visibility', 'hidden')
        return false;
       
    })
    $('#closeComment').show().click(function(){
        $('.storyBox').animate({"opacity": "1"});
        $('#formComment').slideToggle();
        $('#respond').fadeIn().css('visibility', 'visible');
        return false;
    })
should i put $('#formComment') in a var ? does it makes a different?
cheers chris!
