Is there a way to get the blank paper by cheat?

[DraGGon2k]

Hello,

I'm in Shaft 12 in the room where you have to turn the light off and see all the crazy writing on the wall. I searched the room(s) 20min for the key code but couldn't find it, so I checked up in a walkthrough and read that I had to go to Shaft 13 first in order to get some blank page which is required. However I didn't do that, and certainly don't feel like doing that either since it would probably be impossible by leveldesign(crossing the steamplatforms from the other side, etc.).

So is there any way I can continue?
