[Moo] NoobSlide + arrow keys navigation problem

[khosis]

Hey,

I've set up a nice noobSlide gallery plus added HTML param capturing
so I can call the slide at any image I need (it's working really
neat).

Now, I thought it would be even greater if I could browse using arrow
keys. So, I found a proper script:

http://www.openjs.com/scripts/events/keyboard_shortcuts/shortcut.js

And it's working just fine giving ie. JS alert whenever key is
pressed, like:

shortcut.add("Left",function() {
        alert("Left pressed");
},{
        'type':'keydown',
        'propagate':true,
        'target':document
});

But I wasn't able to hook up the noobSlide action (like OBJECT.walk).

Any ideas how to call the OBJECT.walk method using previousIndex and
nextIndex properties within scortcut.add function?

Regards and big thanks in advance
