i'm assuming you don't know what it is?
Unfortunately, no. It works once and then it doesn't need to be inputted again, so I never bothered to remember it. Just use a bunch of key combos, like including the SHIFT key and stuff. If all else fails, just put you palm down on your keyboard and hopefully press enough keys to somehow hit the combination.
Even if I did know it, I can't just up and go saying it in the thread, because the dev owns it and is really adamant on deleting anything that leaks any information or builds of Patreon stuff. Really annoying, it is. But, it's their thread. What can ya do?
