javascript - Using jsfiddle: how can I use underscore.js or backbone.js libraries?

In jsfiddle is possible to use for example jQuery.
But I cannot see any references, for example, to underscore or backbone.js.

Uncaught ReferenceError: _ is not defined

Add the URL for the required library under the "Add Resources" button on the left hand side.

See http://jsfiddle.net/alnitak/BwHxv/

I'm using a self-made jsfiddle base with log included in the HTML, so you don't have to open developer tools :

Includes Backbone and Underscore

I usually started out from this: http://jsfiddle.net/dandiebolt/auHFG/

This comes up as the first result when searching for "jsfiddle underscore".
