Hello, I bought a bluetooth keyboard and it works fine with the rpi. There is just one issue, there is no Alt Gr key on it.
I am used to this key as the modifier for example to write @ and ~. I once found an online description to change the behaviour of Caps Lock to the mentioned key, but after searching for 2 hours now I am not able to find it anymore. I had to reset my rpi and therefore lost these changes. I can remember that I changed the keyboard config file but not exactly how. I have a rpi 4 and it runs on Raspbian OS, any help appreciated
