Screen provides you with an ANSI/vt100 terminal emulator, which can multiplex up to 10 pseudo-terminals. On startup, it executes $SHELL in window 0. Then it reads $HOME/.screenrc to learn configuration, keybindings, and possibly open more windows.

C-a ? (help) Show all keybindings.

C-a c (screen) Create new windows.

C-a SPACE (next) Advance to next window (with wraparound).

  C-a C-a       (other)         Toggle between the current and previously
                                displayed windows.

C-a 0 (select n) Switch to window n=0 ... 9.

C-a 9

C-a w (windows) Show a list of window names in the status line.

  C-a a         (meta)          Send a literal C-a/C-s/C-q to the
  C-a s         (xoff)          process in the window.
  C-a q         (xon)           For instance, emacs uses C-a and C-s.

  C-a l         (redisplay)     Redraw this window.

  C-a W         (width)         Toggle between 80 & 132 columns mode. 

  C-a L         (login)         Try to toggle the window's utmp-slot.

  C-a z         (suspend)       Suspend the whole screen session.

  C-a x         (lockscreen)    Execute /usr/bin/lock, $LOCKCMD or a 
                                built-in terminal lock.

  C-a H         (log)           Log stdout of window n to screenlog.n.

  C-a C-[       (copy)          Start copy mode.  Move cursor with h,j,k,l.
                                Set 2 marks with SPACE or y.  Abort with ESC.
                                (C-[ is ESC.)  Preceeding second mark with
                                an a appends the text to the copy buffer.

  C-a C-]       (paste)         Output copy buffer to current window's stdin.

  C-a <         (readbuf)       Read the copy buffer from /tmp/screen-exchange.
  C-a >         (writebuf)      Write the copy buffer to /tmp/screen-exchange.

  C-a d         (detach)        Detach screen. All processes continue and may
                                spool output to their pty's, but screen
                                disconnects from your terminal.  

  C-a D D       (pow_detach)    Power detach.  Disconnect like C-a d but also
                                kill the parent shell.

  C-a K         (kill)          Kill a window and send SIGHUP to its process
                                group.  Per default this would be C-a C-k,
                                but it is redefined in the demo .screenrc
                                (think of killing a whole line in emacs).

  C-a :         (colon)         Online configuration change.

See the man page or TeXinfo manual for many more keybindings and commands.

screen -r [|]
Reattach to a specific detached session. The terminal emulator reconfigures according to your $TERMCAP or $TERM settings. When you have multiple screens detached, you must supply the session name.

screen -R reattaches to a detached session or (if none) creates a new session.

screen -d [|]
Detach a screen session remotely. Has the same effect as typing 'C-a d' on the controlling terminal. 'screen -D' will power-detach.

screen -list
screen -ls
screen -wipe
Show all available sessions and their status. Use -wipe to remove DEAD sessions.

If sockets are missing, you may send a SIGCHLD to its 'SCREEN' process and the process will re-establish the socket (think of someone cleaning /tmp thoroughly).

screen -h 200
Starts a new screen session and sets the number of lines in the scrollback buffer to 200. The default is 100 lines.
