Q: My new wireless keyboard uses the key positions of the old keyboard

I am using a wireless keyboard to type this question...the letters work fine its the characters and the corresponding keys that are not working.  I have downloaded all the updates, it looks like a simple setting issue.  The computer seems to still think it is using the old key positions.  Thanks for the help, I am suprised this is not a common problem with a troubleshoot answer on apple online support
