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'. Note:Handling C-s and C-q with flow
control, for usage and implementation details.
To bind other keys, use `keyboard-translate'. Note:Swapping
keys, for usage details. To do this for an entire site, you should
swap the keys in `site-lisp/site-start.el'. Note:Handling C-s and C-q
with flow control, for an explanation of why `site-lisp/default.el'
should not be used.
* 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.
