I noticed something strange on the latest iPadOS developer beta. The Fn key on my Apple Magic Keyboard (the old Bluetooth one, not the expensive new iPadPro peripheral) now has two new functions that kind of conflict with each other.
First, Fn-Backspace finally works as “forward delete” as it always has on the Mac. (That not being supported on iOS has long been a source of occasional frustration for me.)
Second, Fn, by itself, calls up the emoji picker, which used to be only called by Control-Command-Space.
Unfortunately, using Fn-Backspace calls up the emoji picker, which means I have to dismiss it (via Esc) if I want to forward delete. That does not save a keystroke, and makes “forward delete” not worth it.
