Buttons to go to previous/next article

[csolisr]

As it currently stands, the News app only has two ways to move to the next article in a feed:

• by scrolling down manually
• by pressing the Right button on the keyboard to go to the next article

I would like to have the option to click on a button to jump to the next or previous article in the feed, in particular on mobile where the option of using the keyboard is not natively available.
