[Karennina]

can anyone help me please, my laptop has additional numbers and symbols in blue last night my cat jumped on the keyboard and now all the keys with the blue on need a blue button with the letters Fn on also i can not access some of the symbols on the top row, it is usable but a right pain i just want it back to normal, thanks for any help

On mine there is a key with "scroll lock" in blue, is it that button that has locked the Fn key on?

Bewva you are a star, I did not even think my post had gotten on here, I just tried a combination of that key the fn key and nums LK and it has worked, thank you so much I could not afford £50 this month to take my laptop to the shop, the power of cbf works its magic again
