PreferencesWindowController (as a top-level member of the responder chain) doesnt forward any selectors to content, specifically the selected view controller. And since PWC is also final you can't subclass to do so. So there are 2 solutions:
make PWC open so folks can subclass and handle responder chain actions at that layer
forward the selected view controller for possible handling of responder chain actions
I will make a PR that focus on option #2 as I prefer PWC to be pretty self contained and if all actions are forwarded properly, we can accomplish what we want at the VC level
