List browsing 
In a list, browsing is possible in two directions:  pressing scroll up key moves the 
focus one step up (backward), and pressing scroll down moves the focus one step 
down (forward). 
When browsing, the item in focus must always be visible. The detailed rules of 
moving the focus are as follows: 
If the choice item that is becoming focused is already fully visible, all the items 
stay in their current positions, and highlight is moved from the old item to the 
new item.
