Keyboard arrow keys navigation with Easy Slider 1.7

I'm trying to edit the Easy Slider to allow the keyboard's arrow keys to navigate the slideshow.

I tried editing the javascript's animate function from:

default:
t = dir;
break;

...to:

开发者_C百科default:
t = parseInt(dir);
break;

...but that didn't work.

Does anyone know how to use the keyboard's arrow keys to navigate this slideshow?

Assuming your next and prev links have IDs of #next and #prev:

$(document).keydown(function(e){
    if (e.keyCode == 39) { 
       $('a#next').trigger('click');
    }

    else if (e.keyCode == 37) {
         $('a#prev').trigger('click');
    }
});

I'm also not familiar with easy slider, but if they have a way to programmatically switch the slides back and forth, then you could swap out the triggers with those. The posted solution will work fine though.
