Just wanted to share a very old article I stumbled upon a few day ago. It is a small into to GNU screen and can be found here http://www.linuxjournal.com/article/6340.
Like many other vannabe *unix natives I have being using screen on and off for different tasks, but not very efficiently. Basically I just used it to launch a process and then Ctrl-A+D to detach and get back later with screen -r. Just recently discovered that screen is a very power full tool for doing your every day work.
Now the first thing I do when opening my laptop is "still" to open Chrome but the second thing I do now is to type screen in my terminal and hence spawning windows within screen with all the stuff I need. But in order to work efficiently with screen you need to know the basics of navigating between windows, copy-paste and so forth. All this a more is covered very nicely in the article above.
