I'm sure @peternlewis will fix that ASAP, but the more interesting news is that this key seems to be available as a shortcut for triggering a Keyboard Maestro macro, which gives some interesting possibilities that I look forward to testing out.
IIRC, we could never assign a Keyboard Maestro macro to just pressing the fn key on previous keyboards.
I haven't tested it extensively, but in what limited testing I did the other day, it did not seem possible using Keyboard Maestro alone… but it might be possible if it is configured in Karabiner Elements.
I just remembered this and tested it… I was expecting that we could use the Globe key as a new hyper key, but Keyboard Maestro 10 does not seem to recognize it at all except and unless it is pressed by itself.
