Hi I'm new to Mac. I have a macbook air and for some reason the top keys, ec, f1 etc etc are not functioning and emitt the non function noise when pressed. Also the volume keys don't adjust the volume. Have I done something to disable them?

I don't have the same version of OS X here but try System Preferences>Keyboard. Is there an option similar to "Use the F1, etc, keys as standard function keys"?
If so, and it has a checkmark, uncheck it & see if that does the trick.
