Re: @key broken

[Alfred M. Szmidt]

         {\tt \backslash}$\langle${\rm CR}$\rangle$
       or
         {\tt \backslash<CR>}

   I'm baffled.  Why the backslash?  As a casual reader, I would never
   think that a backslash somehow means the name of a key.

       Any other ideas?

   So far my favorite option is to leave it as-is: {\tt CR}.

I like this as well, it is also used in Emacs.
