How to transfer defined keystrokes

I'm sure it's been covered in here somewhere, but I cannot find it.

Upgrading from V11 to V12, I'd like to keep my defined keystrokes from
(right-click on menu bar) --> Customize --> Keyboard.

Is there a file or a registry key which can be copied from V11 to V12?
