How do I see ID on minecraft blocks, if I am on laptop

I know I need to do F3+H to see the ID. But I am on my laptop which means I have a volume button on my F3.

I would use ID minecraft site but I am using modded blocks too. I’d apreciate if anyone knows how to help or is someone had the same problem

(Edit: I tried to gold Fn+F3 then click H, even hold all the buttons. I have JEI too and it does nothing)
