I am a very old user of Gnu Screen, actually I am one of those who will suggest noobs to use these better tools for servers. Gnu Screen is awesome tool. It has helped me of good help always and it will. But It very hard to configure and explore for new possibilities. If a tool is unmaintained for a long time it gets outdated. Recently I found a replacement of my age old tool. The Tmux!
Tmux is really great and very easy to use. Best part is you can set all your old shortcuts here too. 🙂
To install it in mac do
$ brew install tmux
$ sudo apt-get install tmux
You can put your setting in
# set -g default-terminal "xterm-color" set -g terminal-overrides 'xterm*:smcup@:rmcup@'
This should be enough to get you started. Google for Tmux cheat sheet to know popular shortcuts. Here is the one of them. http://cheat.errtheblog.com/s/tmux
