Global Menu should receive keyboard command combinations even if a file browser window is the focused window.

[PaulMcClernan]

In Filer I should be able to hit Command+1 and Command+2 (and how about 3?) to switch between List view and Icon view, currently that only works if the Global menu has focus and the view menu is open, but that should probably be handled the Filer instead of, or in addition to being available from, the global menu .

Also keyboard command to go up to a parent directory in a new window while closing the previous window should be command+option+UpArrow not command+SHIFT+UpArrow as the Filer has it. Then again that's my subjective opinion, but it's an opinion that is based on 30 years of macOS 'muscle memory'.
