While beta testing my 3rd level in my new battleback I planned to use the alt+4 shortcut to quit, but instead of hitting alt+f4, i accidently hit ctrl+4 which cut my resolution to about 500 ish. I continued until about 300.

I just thought this would be a neat trick for people who are making jj1 levels with jj2 and would've liked a shortcut instead of openeing the window.
