is a core part of the chat infrastructure, you can interact with it with your JavaScript console and JS scripts. As far as I'm aware there's no documentation on its API, so all I can suggest is have a gander at the chat scripts on Dev Wiki as they may use  and check out the official repository over on GitHub for Wikia Chat.

I'm assuming you have an intermediate amount of JavaScript knowledge already.
