title: Why doesnt my 's' key work in the Python repl?
body: <p>I am experiencing a very frustrating problem when trying to work in the REPL.  For some reason, the "s" key does not work, so I can only type commands that use the other 25 letters of the alphabet.  </p>
  
  <p>I have tried this with at least three or four different versions of Python, and always the same result.  I can type my "s" at the command line, and of course I can run my code from a file, but within the REPL I have to be "s"-less.  </p>
  
  <p>I have checked my readline config to make sure there is nothing funky going on there, but I don't know what else could be happening.  </p>
