How do I fix this...
 

Okay, I read the FAQ on how to make it so that a window closes when you hit ESC, but Im not sure which file to modify.

I want to make it so that when I hit the ESC key, my Inventory window closes. (The window that shows your paper doll, gear, and all the other info when you hit the "I" key)
