Where is the Mac meta key?

I can’t find any reference to a Mac meta key outside the Dorico Key Commands page.
An internet search seems to say that this has turned into the Alt key - but that is also used by Dorico.

Any suggestions please?

It’s the one labelled “control” or “ctrl”. On my keyboard it’s to the right of the “fn” key and to the left of the “Alt” key.

Ooh that was quick.
Thanks very much Leo - I had only ever heard it called control or ctrl.

I suspect the code that generates the key commands page is used for both Windows and Mac, and the fact that “Cmd” (on Mac) = “Ctrl” (on Windows) means that “Ctrl” can’t be used to mean something else on the Mac page.
