Screen as window manager

In case that you didn't know screen is a window manager and a very useful one however for consoles ...
This is my .screenrc file

hardstatus alwayslastline
hardstatus string '%{= kG}[ %{G}%H %{g}][%= %{=kw}%?%-Lw%?%{r}(%{W}%n*%f%t%?(%u)%?%{r})%{w}%?%+Lw%?%?%= %{g}][%{B}%Y-%m-%d %{W}%c %{g}]'
# Default screens
screen -t shell1 0
screen -t shell2 1
screen -t shell3 2
screen -t shell4 3

To switch between screens type CTRL+a 0 - goes on screen 0 - replace 0 with 1-3 to end up on a different window(screen)

To detach is a simple CTRL+a d - this will put screen into the background and you can reatach with
screen -r or if you have multiple sessions
screen -ls will list the screens that you have running and then
screen -r sessionName
