A handful of these have been present for years (they weren't new in Monterey)-- specifically the ones replicating keys that are not present on Apple's laptop keyboards (Fn+Delete for forward delete, Fn+Up for page up, Fn+Right for Home, etc.). The ones that map to OS functionality (rather than to other keyboard keys) are definitely new-ish, though-- like Fn+H to show desktop, or Fn+M for the Apple menu.
