jQuery Sortable Move UP/DOWN Button

Question

I currently have a jQuery sortable list working perfectly. I am able to move the \'li\' elements around. However, how can I make a button to move a specific \'li\' element u

Although the answer by Azatoth works fine, bobby might be looking for an animation, like I did. so I wrote the following code to make the movement animated:

function moveUp(item) {
    var prev = item.prev();
    if (prev.length == 0)
        return;
    prev.css('z-index', 999).css('position','relative').animate({ top: item.height() }, 250);
    item.css('z-index', 1000).css('position', 'relative').animate({ top: '-' + prev.height() }, 300, function () {
        prev.css('z-index', '').css('top', '').css('position', '');
        item.css('z-index', '').css('top', '').css('position', '');
        item.insertBefore(prev);
    });
}
function moveDown(item) {
    var next = item.next();
    if (next.length == 0)
        return;
    next.css('z-index', 999).css('position', 'relative').animate({ top: '-' + item.height() }, 250);
    item.css('z-index', 1000).css('position', 'relative').animate({ top: next.height() }, 300, function () {
        next.css('z-index', '').css('top', '').css('position', '');
        item.css('z-index', '').css('top', '').css('position', '');
        item.insertAfter(next);
    });
}
