I don't however know as if anyone using a newer Mac keyboard would
figure that they could press option help to get the functionality
of the 'insert' key, which I don't think ever did much on the Mac.
IIRC Apple stopped that when they retired ADB, i.e. around the time
they retired the beige boxes. And since Laptops (which still used ADB
a tad longer) don't have these keys, I doubt anyone targeting OS X
can use that. But we're getting off-topic, so I'll take more musings
on this off-list :-)
