whenever i try to play minecraft, the keyboard is kind of messed up, when i try to type the letter "a" "A" , it highlights all of my typing then delete it all. It also won't let me type in some letters.

Hardware issue, the control button is stuck.

Edit: Duplicate of MC-3643.

Note that sometimes it's the right control key that gets stuck, even if you rarely use it. If you press both control keys and then release them, then it should work.

Duplicate of MC-886; according to @unknown's comments there this isn't necessarily a hardware issue but still isn't something that can be directly fixed:

LWJGL issue, we can't help it as we cannot update right now.

I have no right control key
