I use Macos/linux at home and win at work. And all with the same keyboard, because it has a dedicated macOS and win/normal mode. And yeah, the us intl. keyboard works across win/Linux, but I dislike having the hyphens key as a dead key so i only really use it at work where I can’t skip umlauts. In private I don’t really need them and should the day come I’ll copy them from ddg or something.
