Used to be even lazier when clicking the reddit random button page.
Item used to make it even easier to find some random subreddit on reddit.
Press the 'r' key to find a random subreddit, and press the 'b' key to go back to the last subreddit visited.
Also can toggle the key action on or off. When its off, will allow you type whatever you like without having the page refresh to something when pressing 'b' or 'r'.
