Octohint adds IntelliSense hint to GitHub. With Octohint installed, when you view code at GitHub (For example this demo), you'll get features as follows: - Mouse Hover: Show information of current token - Left Click: Show all references of current token - [⌘] + Click: Go to definition of current token (For Windows and Linux user, use [Ctrl] instead) Octohint is a pure client thing. All code analysis are performed at your browser, which means your code and actions log like click, mousemove will never be sent to any server.
