New(?) keyboard shortcut for full screen
I've long been familiar with the Control-Command-F keyboard shortcut for toggling an app's Full Screen view, as listed here: https://support.apple.com/en-us/HT201236. However, today I noticed Chrome wasn't responding to this shortcut so I checked the View menu, and it showed the shortcut is Fn-F, which isn't listed on the page I linked. Is this new?
It's also inconsistently applied. Firefox only recognizes the Control-Command-F shortcut, while native apps like Finder and TextEdit recognize both Control-Command-F and Fn-F. So this isn't just a third-party app thing. I'm interested in learning any additional details about this that the community can provide.
