Ease Scroll

1

how would I change this code:


up_arrow.onRelease = function() {
    form.body_txt.scroll--;
};

down_arrow.onRelease = function() {
    form.body_txt.scroll++;
};

…so that the scrolling eases. I am assuming that you would instead of say “++” you would assign a number like 3 and then divide the number by the ending point. But, even though that sounds simple enough, I’m not sure how to apply it in this sense.

Thanks
