What command did you use?

No, but I do know that Edwin can be a nasty editor on some PCs. You should better use DrRacket, a recommendation on which I've got here in the study group. It is essentially identical to Scheme with the major difference of being furthermore convenient and not issuing annoying messages such as the one you've encountered. Simply google "DrRacket Scheme download".
Have good luck!

While in the '*scheme*' buffer, M-o is undefined.  You can only use M-o in other buffers.  This is stated in the Evaluating Code section of the Don't Panic pdf.
