On Mac OS I tried adding keyboard shortcuts using the linked Apple support
document to allow for comment/uncomment bindings in DrRacket and it doesn't
work (at least on Mac OS Monterey). One thing I noticed is that if you go

Hi Matthew
Thanks for the fast reply! Well I have to apologize - I had skipped the
"dist" step. For some reason I assumed incorrectly the dist was if you
were building for another OS vs hardware architecture. I ran your test as
well and it worked perfectly. Thanks again!

has it would use Rosetta 2
to run the code.
So my question is, is there a way to build a universal binary for Mac OS or
should I just build one on each platform and have separate binaries.
Thanks for any help.

Opinions are like belly buttons, and I'd like to show you two of mine (as in
that terrible Gene Roddenberry film).
I very much like the overall goals of making Racket more consistent and more
generic. They strike me as reforms of the language. I wonder if adding these
features would be too f
