"Parallel mode" for GNU Screen?

[Ethan Mallove]

Hi,

Is there a "parallel mode" of some sort to make Screen copy commands from one
window into other windows? I'm seeking an alternative to the "at" command. I'm
basically looking for behavior in Screen that would work similarly to "cconsole"
(see http://docs.sun.com/app/docs/doc/819-0582/6n30g7ie3?a=view). Something
like, e.g.,

  :set parallel mode

Then anything typed in one window would also be copied into all the other Screen
session windows.

Is there a way?

Thanks,
Ethan
