I have an American or English keyboard, I'm not sure. In any case, I have entered the German key setting and it does not work, why… I do not know. I do not know how I do a question mark. You know that. I have a google chrome asus notebook.
You would have found information about that if you had searched under https://www.giga.de/...t-aendert/
You can find the assignment of the keys under
