The Move*() method moves the *internal* cursor of the ListView. This cursor is
intended to let you loop throug every ListView item. The ListView.Item
returns the current item pointed by the internal cursor.
To change the visible selected item, use the Selected property of the item.
ListView.Current returns the current selected item.
