Manjaro with ASUS F45A - Still testing

Greetings!!!

This might be an easy one.

I am new to Linux and am still testing Manjaro via Pen drive. I own a ASUS F45A notebook, something like 9 years old.

Everything works fine, except the fact that I cannot use some keys : I need to press "control + alt + Q" to use the “/” and "control + alt + W" to use the question mark. Unfortunately this does not work in Manjaro. Tried several keyboard configurations to no avail.,

Any solutions/suggestions anyone ?

Thanks in advance.

Best wishes.
