<p>Vertical lists are used extensively in most applications. Two-dimensional
grids are less frequently used, but have obvious advantages in some situations.
In lists and grids, the user can move the focus from one item to another using
the Arrow keys. This is called browsing or scrolling.</p>
<p>In devices supporting touch, a menu item can be opened by
touch down and release.</p>
<p>In general, vertical browsing is preferred over horizontal browsing; the
keypad solutions should take this into account.</p>
