Question 1: How to turn two levers at once during a performance? Question 2: is there a console in the game? And there is no question: In the window at the library you can see the latest location (for those who are interested)
1.) To turn 2 levers in the theater at once, you need to be running on an older patch of the game as this was fixed in one of the newer versions, including current patch. The download for the patch we do runs on is in the resources tab.
Once you have that patch downloaded, you use the wasd keys to highlight one of the arrows while you hover your mouse over another one then mash both your interact key and mouse 1.
2.) I don't believe there is a console, no.
Also yes, we did know you can see the last area from that window. There's not much out there, so they probably didn't expect anyone to actually climb up there and look out of them.
