Screen is a command-line tool that lets you set up multiple terminal windows within it, detach them and reattach them later, all without any graphical interface. This program has existed since before I started using Linux, but first I clearly need to address the fact that I'm even using Screen at all prior to writing a tech tip about it.

So now that those arguments are out of the way, I thought those of you still using Screen might find it useful to learn how to do copy and paste within Screen itself.
