Now I will confess something that will make even Dick say that I live in the stone age and that I should go with the flow instead, but unfortunately I can't read your QR because I don't have a smartphone!
It is a bit of a mess and a fiddle on my mini (cut down) keyboard without a special numeric keypad.
I have to press the (blue) 'Fn' key and then while holding down the 'Alt' key press the blue numeric keys (which are also normal keys in another mode). Then remember to de-select the numeric mode. Makes you want to go and ask / tell 'Alexa' or similar
