Keyboard typing strange symbols
Seemingly out of the blue, my new Mac´s keyboard is changing some keys to different symbols. For example, the "at" symbol usually employed when hitting shift and the 2 key, now creates quote symbols. Not all keys are affected, but many of the number-punctuation keys are not using standard US English. I followed the directions given in an earlier post, going into Keyboard settings and reselecting US English, but the problem persists.
