+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.
