I don’t know yet what the right solution is though (a number of APIs that are exposed through PyObjC can be used to implement similar functionality).

If there were a more modern solution I'd gladly use it rather than asking you to expose gross and ancient Carbon APIs :).  Which APIs that are already exposed can do this?

>> The cautions that the relevant Carbon APIs require 32-bit mode are inaccurate; https://blog.shpakovski.com/2012/07/global-keyboard-shortcuts-in-cocoa.html <https://blog.shpakovski.com/2012/07/global-keyboard-shortcuts-in-cocoa.html> explains that they're still supported in sandboxed Mac App Store apps, so they're just poorly documented, not deprecated.  (It seems that there's never been a proper Cocoa replacement for this functionality, just a couple of popular wrappers floating around out there…)

Thanks!

Sure, sometime this weekend I'll try to write it up.
