Allow users to upvote stories by pressing "a" on keyboard.
Allowed users to navigate up/down through comments when viewing an item
Added options page to enable/disable keybinds for the plugin
Merge branch 'allow-toggle-keybinds' into enhance-keyboard-navigation
Fixed bug where trying to navigate with next/previous keys when there were no more results, would cause TypeErrors to be thrown
Created focus_next function to reduce repeated code
Removed check for users inputting "h" key, as the method "open_help" did not exist on the HN object, and was throwing errors when pressed.
Removed unnecessary comment/variable from options.js
Fixed a big whoops, that prevented the next_story and previous_story from being called on any page other than root. Next/Previous story will now work on any page that uses the class "post_title" for content links. (example: /ask)
Users can now press "l" to open both the story and comments in background tabs. Added background script to allow access to chrome.tabs.
Merge branch 'open-stories-and-comments-in-background' into enhance-keyboard-navigation
Prevents comments tab from opening if the story url is the same (site submission)
Fixed bug where hotkeys would remain active when typing in HN Submit overlay
Pressing "a" will now also upvote selected comments. Added some extra comments to functions
