So for some reason, the esc key on my keyboard doesnt work. Idk why (stilling troubleshooting but i have ruled out a mechanical issue), but as a result i cant access the pause menu in-game- so no mcm, saving, exiting, etc for me.

I was wondering if there is a way to to change key bindings for the FONV outside of the game- since i cant open the pause menu to do it in-game? I just want to change the keybinding for the pause menu to another key.

Do you have a 360 controller. If so plug that in and get access to the menu and then unplug it and you should be able then to make changes to the config.

The other option you would have to go to the FalloutPrefs.ini which is located in your documents folder. You would need to know the code for different keys. I do not know which ones are which.
