[Where is Party AI in Game Files?]

I've been tearing PFK apart trying to find where the party AI is scripted, but I can't find it. Does anyone know where it is? I need to mod this badly.

[Rebinding the Escape Key]

Okay, Ive got a weird one here...

 

The escape key stopped working on my laptop keyboard. Needless to say, it makes playing games surprisingly difficult. I am trying to find a way to open the menu with the letter O key. Im guessing this might be possible with FOSE, but I am not sure how I would go about scripting something like this.

 

Help a brother out!
