No more coordinates in Minecraft?

I have a little problem in Minecraft. I tried to display the coordinates with F3, but it doesn't work. I've tried everything possible (e.g. Reduced debug info to false) but nothing works. What's important is that the F3 key on my laptop is responsible for volume, and you can't change that…

What kind of laptop do you have?

Lenovo Yoga

In the settings there should be a keyboard option where you can set the f1 etc. As standard function keys

Ok I'll take a look

Well, that's not possible

You have to press the fn key at the same time

First press the key combination Fn + ESC. Then the mode switches from the volume buttons to normal. Like before. Then just press F3.

^ Thanks

Thanks now it goes ^ - ^

Press Fn + F3

This is the case with many laptops.

Thank you
