Shortcuts suddenly don't work any more..?

Can’t say I’m in my element here, but I think so…

That works OK for me, though I tried a different shortcut: it brings up the Audio Export dialog as expected. Can you do Help > Create Diagnostic Report and attach the resulting zip file here? I can then take a look at the actual JSON file, which is included in there.

Thanks for staying with this. Here’s the file.

I’d also be glad to try the key combination that worked for you.

Your pictures above show “Meta+Ctrl+Shift+E”
Make sure you are pressing all of the keys.

Somebody please correct me if I am wrong, but I think that on a Mac:

Meta is the ctrl key (Control)
Ctrl is the cmd key (Command).

so Meta+Ctrl+Shift+E equates (on a Mac) to ctrl+cmd+shift+E.

Yes, indeed, Steven, that was it! Thanks very, very much to you and Daniel for all your help.

Great point about the diacritic beating the shortcut to the punch, Pjotr. Never would’ve thought of that. Thanks.
