Hello. I bought a new keyboard a couple of weeks ago and it works great. I have noticed two flaws though, because there are no aparent escape ke y or tab key. It’s a sandstrom keyboard but I do not know the model. I believe Sandström is Norwegian. I am not sure but believe so. I have this wierd symbol with a square but cannot find the escape or tab key and nothing happens no matter what I try with this square key. Thanks for any advice.
