Nice list.

Also, hidutil (https://developer.apple.com/library/archive/technotes/tn2450...).

Example:

     hidutil property --set '{"UserKeyMapping":[{"HIDKeyboardModifierMappingSrc":0x700000049,"HIDKeyboardModifierMappingDst":0x700000065}]}'
For my PC keyboard, remaps "Ins" (normally useless under macOS) to something ("PC Execute") I can trap and remap with Keyboard Maestro.

    hidutil property --set '{"UserKeyMapping":[{"HIDKeyboardModifierMappingSrc":0x700000064,"HIDKeyboardModifierMappingDst":0x700000035}]}'
Remaps top left key on Euro-style keyboards from useless "paragraph" to useful "backtick".

not to be confused with hdiutil:

    hdiutil detach /Volumes/some-usb-drive

    hdiutil makehybrid -joliet -o foo.iso ./srcfolder/

There's a nice generator for these mappings https://hidutil-generator.netlify.app/

Yes, this is great... I was given a Macbook with a Norweigan keyboard for testing a port of FreeBSD on it, and I quickly discovered that the keyboard layout remapping stuff available via the UI won't remap at least this one key to what I'd find on my US keyboard.

Oh wow, this is amazing. I had been unable to _swap_ esc and caps lock on the mac until now.
