There are a lot of default shortcuts, and they’re almost all
customisable. It might be worth adding some text about how changing
the behaviour of the modifier keys in Emacs doesn’t change their
effect in macOS.

But I think that bit of the manual, modifier keys (macOS), could do
with being rewritten. It’s slightly misleading and doesn’t mention the
ns-command-modifier variables at all.

Wow, indeed, you're right.

I say "wow" because I was extremely sure I'd been using Command-$ (as
M-$) semi-regularly on MacOS for years. However, this morning I tried
this at several commits a ways back, and it's clear I was
mis-remembering or hallucinating or something :)

Thanks, and sorry for the noise

If this cannot (or shouldn't) be fixed, how about mentioning it in the

Hmm, what’s happening is that macOS is going into a screenshot mode.

I don’t know if we can over‐ride this, and I don’t know that we’d want

By default, the "command" key in MacOS is bound to "super". If I type
s-$, Emacs seems to wait for input that it never receives. Anything I
type afterward appears to be ignored, except `ESC ESC ESC', which gets
Emacs out of this state. However, even hitting `C-g' repeatedly does
not.

The issue seems to be related to the command key rather than to "super"
or to the command bound to the key. In my configuration, I map command
to meta, and the same problem happens when I use M-$ to `ispell-word'.

Using `M-$' with command as meta worked until relatively recently. It
would be great if it could be brought back or made to fail more
explicitly.

Please let me know if I can provide any additional information.

Thanks,

John
