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
