Different key mappings on Multiple Keyboards?

I agree. I can imagine that it should work well in most cases, more so if you limit it to certain use cases.
The benefit is that we can avoid using Karabiner-Elements.

My concern was that the Delete key might accidentally delete something that cannot be recovered. I just had one a few days ago:

A Quick Way to Undo (Such as Deleting Variables) in the Preference?

Hi, I wanted to delete the value for a variable, but accidentally deleted all variables (⌘A → delete). [image] Thankfully, I have TimeMachine backup a few days ago. This got me to think: Is there a way to undo any operation in the Preference? I tried "Revert Macro at Editor Launch" and it won't recover the variables. It would have been disastrous if I did not have TimeMachine backup.

Also, Karabiner-Elements offers more options:

I'm not against your implementation at all. I think it is a very creative way to handle the USB keypress issue. I have not thought of this solution before! I appreciate your sharing your solution! Karabiner-Elements, on the other hand, is probably for those who are comfortable with JSON file and want more capabilities with a single key.
