Just yesterday, I bought a laptop and I set it up. Everything works and it's great, but, the F3 key isn't working on Minecraft. Outside of Minecraft, the F3 key is responsive (it brightens the screen), but just not in Minecraft. If you're wondering, I'm using a Windows 8 HP Pavilion laptop. Remember, I just got this laptop yesterday, so don't go saying my keys are bad or something.
Thanks in advance!
