New interface/access method - scroll wheel to navigate. Switch/Key/LClick to select

[willwade]

We have some users who can control a scroll wheel on a mouse. A totally different access solution is to use a scroll wheel (so scroll up/down - with a switch/keypress/left click to select).

This obviously would only need to work on the Web version currently.

I guess something like..

    var _top = $(window).scrollTop();
    var _direction;
    $(window).scroll(function(){
        var _cur_top = $(window).scrollTop();
        if(_top < _cur_top)
        {
            _direction = 'down';
            // Activate/Hold down key
        }
        else
        {
            _direction = 'up';
            // Activate/Hold up key
        }
        _top = _cur_top;
        console.log(_direction);
    });
});​

Would this also work on iOS though if someone swiped up/down?

Mouse wheel event is available. https://developer.mozilla.org/en-US/docs/Web/Events/wheel And swipe is captured with touch events. Apparently wheel event can capture wheels that support two axis movements.

Have some users where swipe is the main access method. Not sure if this fits here: Swipe Up/Down to navigate up/Down the tree and swipe left/right to access the tree elements. That would be neat
