It's a pitty that we need to add a configuration option, for many users it is not going to be easy to discover it. macOS doesn't have this issue, so there must be a way of detecting the keyboard layout... Unless they apply the quirk on user space checking the selected keyboard layout and language in settings. I bought ANSI English keyboard to see if I could figure out where is the difference but no luck so far. For what it's worth, Tested-by: José Expósito <jose.exposito89@xxxxxxxxx>
