Currently I can't use C, comma, period, Z, X, V, M, copy or paste using Ctrl+V or Ctrl+X (presumably because I can't use the V or X keys), and I can't use the enter button either. Pressing Shift or using Caps doesn't make a difference, either. Right now I'm typing this with the help of an on-screen keyboard... I've seen quite a few people with a similar issue, but the working and not working keys are always different, and I don't know if that has anything to do with it. I'm using a Gateway desktop computer with a touch-screen function, and a DELL keyboard. They keyboard has worked fine for a long time, and this is the first time I've had an issue with it. I believe it probably had things spilled on it a few times, but was quickly shook of water, or if anything else spilled, it had the keys carefully removed and dried out from the inside. It worked perfect yesterday, and I only noticed it stopped working when I got home today. Help please!
