I don't know Apple's endgame for the Fn/Globe key–or if Apple does
Summary
Marcin Wichary analyzes Apple’s Fn/Globe key history, tracing its evolution from early PC and laptop keyboards to modern Mac and iPad keyboards. The piece argues that the Globe/Fn ecosystem has become increasingly confusing and fragmented across devices, third-party keyboards, and OS shortcuts, leading to a non-sustainable UX. It suggests potential design directions, such as simplifying modifiers or rethinking keyboard layout to reduce cognitive load and improve cross-platform consistency.
