The selection strikes me as arbitrary and outdated, as well as kind of odd: should the default bindings have such dependencies?

And how often does one need to manually refresh? We recommend using a good terminal emulator like urxvt, so that's that, and I can't think of any others that'd benefit. Does anyone actually use this often? Then it might be better to add refresh to a hook.

OK then, I'll send up a few patches implementing these suggestions. They should follow on the heels of this email.
