Enter button not working

[Menno]

Hi, i was testing some Linux-distributions on my laptop and after that i installed Fedora and it worked fine, but after a while when i was working on my laptop i entered an URL in Firefox but when i pressed enter nothing did happen. So i closed Firefox but it didn't work again so i typed something on a notepad and pressed enter, but also nothing did happen, and i can't use commands to and it's really getting annoying can somebody please help me?

Can you try a different keyboard to make sure it is not a hardware problem?
