“I don’t know what is Apple’s endgame for the Fn/Globe key, and I’m not sure Apple knows either”

Every modifier key starts simple and humble, with a specific task and a nice matching name.

This never lasts. The tasks become larger and more convoluted, and the labels grow obsolete. Shift no longer shifts a carriage, Control doesn't send control codes, Alt isn't for alternate nerdy terminal functions.

Fn is the newest popular modifier key, and it feels we're speedrunning it through all the challenges without having learned any of the lessons.
