Basics Screens on linux

I always forge how to use the screen application in linux for ssh sesions. Here the basic stuff to work with screens:

Start
$ screen

Exit and close:
$$ CTRL + D
or
$$ exit

Disconect from the screen program but leaving it opened:
$$ CTRL +A CTRL+D

Reconect to an opened screen program:
$ screen -r

From the screen, create another “tab”:
$$ CTRL+A C

Switch selected tab:
$$ CTRL+A CTRL+A

List existing tabs:
$$ CTRL+A W
