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
