Looks like it's not configurable yet:

         elif e in ("<Esc+r>",):
             self.incremental_search(reverse=True)
         elif e in ("<Esc+s>",):
             self.incremental_search()

This should be fixed. I think it's not there because I was putting it off to see if we could agree to fix it for everyone - ie make the new defaults match readline - but I think that's unlikely at this point.

https://github.com/bpython/bpython/compare/tmp may fix things

is this in production yet?

I see it in master, but not in the 0.14 branch, which gets deployed with pip.

@karolyi Yep, this won't be released as a bugfix, so we'll have to wait for the next release or use master.

@thomasballinger thx. when do you anticipate it?
