@s3thi Alt Gr uncovers a bunch of odd symbols in funny places. Which keyboard layout do you use?
I found in Windows it was actually easy to make my own layout with the keys just as I want them, as I range between British English, German and Swedish and they all have different things in their layouts by default.
Oh apparently the layout creator only works on win10? You can still use the created layouts on 11 though: https://www.microsoft.com/en-us/download/details.aspx?id=102134
Or there's this in Powertoys: https://learn.microsoft.com/en-us/windows/powertoys/keyboard-manager
