I just noticed a small but unexpected response for the keyboard shortcut for Full Screen. While Orion's View menu shows fn-F in contrast to Safari's Control-Command-F, the latter actually works and works best. When I actually do fn-F on my system (MacBook Air), I get different results depending on whether a text box is open on the screen. If so I get an "f" and possibly a switch to fullscreen. On the main screen of this feedback site, pressing fn-F brings up the user login window for some reason. In some cases it toggles between full screen but not always.
I could upload a screen recording but not sure if that will be helpful without seeing as I press the keys? I am assuming this can be reproduced in two seconds in any Orion session on a system with a "fn" key but let me know if not.
I expected fn-F to behave exactly like if I went to View->Full Screen
Alternatively, we really only need either Control-Command-F or fn-F to toggle between Full Screen but not both. I would pick one (Safari's default of Control-Command-F seems fine) and only toggle Full Screen with that key combination. The View menu should of course match. If the shortcut for Full Screen reverts to Control-Command-F then pressing fn-F should work like any other non-mapped keyboard combination.
