My "n" is stuck! lol
So, you have a sticky "n", eh? I know that feeling. I'm afraid I abuse keyboards terribly. My latest is a cordless, wireless model. I spilled a bunch of soda in it when it was less than a week old. Thank goodness pouring mass quantities of alcohol in it & letting it dry out for a couple of days worked. That was months ago.
About a week ago a couple of my keys started to act strange. I halfway took the thing apart & found some little broken plastic thingy wedged where it didn't belong, so after removing it, I reassembled & most of the idiosyncrasies have stopped. It's still not quite right, but there is something just wrong about a keyboard's first set of batteries lasting longer than the keyboard.
