Why isn't my F3 key working in Minecraft?

by S. Morgan   Last Updated May 15, 2018 17:14 PM

I use WorldEdit a lot on Minecraft, so I have advanced item tooltips (AIT) on (which shows the IDs of all blocks). To enable this, I press F3 and H, but on my new computer, I can't enable AIT, nor can I use any of the other F3 shortcuts. I've tried just pressing F3 and H, and I've tried Fn + F3 + H, but neither work. Does anyone know what I need to do?

My computer is a Dell Inspiron 17-5000 i5/8/128, if that helps.
