hidutil - looking for Usage ID of § key

OS: MacOS High Sierra

Following https://developer.apple.com/library/content/technotes/tn2450/_index.html, I'm looking remap they top left key on a MacBook Pro (UK version) internal keyboard using command hidutil. The key is ±/§. The command works as expect when I remap a different key, however, I cannot figure out the correct hex usage ID for the ±/§ key.

The US model has the Grave accent and tilde key in it's place. However, it's usage ID (0x35) doesn't work for the ±/§ key.

Any help is much appreciated.

Hi Reinhard,

The Usage ID you are looking for is 0x64.

This command switches the § key with the 0:

hidutil property --set '{"UserKeyMapping":[{"HIDKeyboardModifierMappingSrc":0x700000064,"HIDKeyboardMo difierMappingDst":0x700000027},{"HIDKeyboardModifierMappingSrc":0x700000027,"HID KeyboardModifierMappingDst":0x700000064}]}'

If you want to restore the original state you can just:

hidutil property --set '{"UserKeyMapping":[]}'

Good luck,

Andris

Most probably the code for this key is 0x32. To make sure, download this free utility (Key Codes) and press required key. App will show you hex code for the key.
