Take a look at Keychron: they make mechanical keyboards of different price levels with the most diversified layouts and features. Usually they have a switch to change from Mac to Win layout and have Bluetooth and wired versions.

Yeah I think it is a new feature of iOS 17, the manual of which seems to be still missing

You’re right, looking for them in Books works really bad. As another commenter said, it looks like for iOS 17 is still not available.

On a side note: I just saw that you can look up an interactive version of the manuals through the “Tips” app. Much more user friendly and it contains everything that is in the eBook - albeit still iOS 16 even though my iPhone is up to date.

There is a very detailed manual with each version of iOS actually. The keyboard is explained too, including this :)

You can find them in Apple Books (Picture in German)
