Controls

-----

RTV currently supports browsing both subreddits and individual submissions.
|

In each mode the controls are slightly different. In subreddit mode you can

browse through the top submissions on either the front page or a specific
|

subreddit. In submission mode you can view the self text for a submission and

browse comments.
