As a very new Emacs user, I've been using Ctrl+w and Ctrl+y to cut/copy and paste between buffers in Emacs. Is there a way to do the same thing so that not just Emacs, but the entire system, can have access to what I am copying and pasting? Thanks.
P.S. I would like to do this in Linux (in a terminal emulator running under X) and Mac OS X (e.g. with Terminal).
