Select items in a list with keyup JavaScript, JQuery

I'm trying to make a list to select items but the behavior when I use up or down arrow is not so good. When I use up or down arrows it scrolls the <div> and also select and focus on <li> tag but the scrolls moves first so it seems to be kind of rare.
How can I achieve the correct behavior using up and down key?

I really apreciate your help Maciej Wojtasik, no, what I mean just look the behavior of the scroll bar when you type up or down, look this site kwfinder.com and try to chose a language, just move the up an down key arrows and see how the scroll bar moves, and se my example and your example, thats the problem and I do not know how to achieve this.
