120: How do I bind `C-s' and `C-q' (or any key) if these keys are filtered

     out?

  To bind `C-s' and `C-q', use either "enable-flow-control" or
  "enable-flow-control-on".  see question 119 for usage and implementation
  details.

  To bind other keys, use "keyboard-translate".  see question 123 for usage
  details.  To do this for an entire site, you should swap the keys in
  lisp/site-start.el.  see question 119 for an explanation of why
  lisp/default.el should not be used.

  NOTE: * If you do this for an entire site, the users will be confused by
          the disparity between what the documentation says and how Emacs
          actually behaves.
