Keyboard

The wireless keyboard has been acting unstable, and finally to the point of annoying. As that's my first one ever, I don't quite know how to trouble-shoot. After a few guesses, it's the batteries! Those came with the keyboard when I got it from A. They were leaking liquid!!! Yikes!!! Totally gross!!!! Luckily, after cleaning up and new batteries put in, the keyboard works fine. I guess I should have been smarter with batteries.
