Hello!
It returns "Cannot read property 'keydown' of undefined" when I'm trying to run it in the chrome console on the SI website. I am totally oblivious to js - is it me doing something incorrectly or it's not supposed to work at all?
Cheers!

Try to run this code in console only when the game is already loaded and the first question was already asked (so you have 'answer' button), maybe it could help. Also, the devs of SI website could change smth on the website.

As I remember it was only a draft and it don't work stable.
Unfortunately, I have no time now for patching/fixing this, sorry.
