Andy,

> Speaking of the platform nuances – this might be relevant to the ongoing platform API discussion.  Right now FX picks up nothing from the preferences set by the user within the OS.  You are right, macOS allows the user to change key modifiers (for example, switch control and command keys, Settings -> Keyboard -> Keyboard Shortcuts -> Modifier Keys) and FX remains oblivious to this change.

Those changes happen at a low level in the OS and are transparent to JavaFX. There’s nothing we need to do there.

We can’t directly query the OS to find a binding like, say, Shift + RIGHT => “moveRight:”. The default mappings are well-established so just re-implementing them is fine. A super power user can alter these bindings by editing a text file and unless we go parse that text file we won’t honor those changes. But that file might contain bindings we can never map (like multi-character Emacs-style sequences) so there’s no guarantee that we can honor their bindings anyway.

A regular old power user (rather than a super power user) would probably use something like Karabiner which remaps things at a low level that’s transparent to us.

TL;DR not a bad idea to honor the platform key bindings but it would be nightmare to test and implement and benefit a very small number of super power users.
