Feature request: support macOS fn (globe) key in keymap

[xezrunner]

In other editors that I use on macOS, such as Visual Studio Code, fn (the globe key on Apple keyboards) can be used as a modifier with keyboard shortcuts:

Despite the warning, the combination does work:

As far as I know:

• on Windows (and Linux?), a "function key" is not defined as a key, since many generic keyboards use it as a reserved modifier in hardware/drivers to do their own functionality (such as backlight, volume etc.)
• in contrast, on macOS, the fn (globe) key, at least on first-party Apple keyboards, is a first-class, valid modifier to use in combination with other keys, at least using NSEvent (https://developer.apple.com/documentation/appkit/nsevent/modifierflags-swift.struct/function)

I do not have access to the closed beta of Jai, so I am unsure whether this is something that's more relevant for an input-related Jai module that's being used here.

I'm not sure whether supporting this for macOS alone would be worth it either, considering other platforms don't define an fn key/modifier the same way.
