+====== SCREEN Quick Reference ======
+===== Getting in ====
+| start a new screen session with session name | ''screen -S //<name>//'' |
+| list running sessions/screens | ''screen -ls'' |
+| attach to a running session | ''screen -x'' |
+| attach to session //name// | ''screen -r //<name>//'' |
+| the "ultimate attach" | ''screen -dRR'' (Attaches to a screen session.  If the session is attached elsewhere, detaches that other display.  If no session exists, creates one.  If multiple sessions exist, uses the first one.) |
+===== Escape key =====
+All screen commands are prefixed by an escape key, by default ''C-a''
+(that's Control-a, sometimes written ''^a'').  To send a literal ''C-a''
+to the programs in screen, use ''C-a a''. This is useful when working with screen within screen. For example ''C-a a n'' will move screen to a new window on the screen within screen.
+===== Getting out =====
+| detach | ''[[commands:detach|C-a d]]'' |
+| detach and logout (quick exit) | ''[[commands:pow_detach|C-a D D]]'' |
+| exit screen | ''[[commands:quit|C-a \]]'' Exit all of the programs in screen. (//not// recommended) |
+| force-exit screen | ''[[commands:quit|C-a C-\]]'' (//not// recommended) |
+| getting out of the screen session | exit |
+===== Window Management =====
+| create new window | ''[[commands:screen|C-a c]]'' |
+| change to last-visited active window | ''[[commands:other|C-a C-a]]'' (commonly used to flip-flop between two windows) |
+| change to window by number | ''[[commands:select|C-a <number>]]'' (only for windows 0 to 9) |
+| change to window by number or name | ''[[commands:select|C-a ' <number or title>]]'' |
+| change to next window in list | ''[[commands:next|C-a n]]'' or ''[[commands:next|C-a <space>]]'' |
+| change to previous window in list | ''[[commands:prev|C-a p]]'' or ''[[commands:prev|C-a <backspace>]]'' |
+| see window list     | ''[[commands:windowlist|C-a "]]'' (allows you to select a window to change to) |
+| show window bar       | ''[[commands:windows|C-a w]]'' (if you don't have window bar) |
+| close current window  | Close all applications in the current window (including shell) |
+| kill current window   | ''[[commands:kill|C-a k]]'' (not recommended) |
+| kill all windows   | ''[[commands:kill|C-a \]]'' (not recommended) |
+| rename current window | ''[[commands:title|C-a A]]'' |
+===== Split screen =====
+| split display horizontally  | ''[[commands:split|C-a S]]'' |
+| split display vertically    | ''[[commands:split|C-a |]]'' or ''[[commands:split|C-a V]]'' (for the vanilla vertical screen patch) |
+| jump to next display region | ''[[commands:focus|C-a tab]]'' |
+| remove current region       | ''[[commands:remove|C-a X]]'' |
+| remove all regions but the current one | ''[[commands:only|C-a Q]]'' |
+===== Clipboard and Navigation =====
+| freely navigate buffer | ''[[commands:copy|C-a [ ]]'' or ''[[commands:copy|C-a <esc>]]'' |
+| toggle selection to copy | ''[[commands:copy|space]]'' |
+| paste                       | ''[[commands:copy|C-a ] ]]''  |
+===== Help =====
+| See help | ''[[commands:help|C-a ?]]'' (lists keybindings) |
+The [[man:start|man page]] is the complete reference.
+===== Scripting =====
+To any session //name//,
+| send a command to a named session                | ''screen -S //<name>// -X //<command>//'' |
+| create a new window and run //ping example.com// | ''screen -S //<name>// -X screen //ping example.com//'' |
+| stuff characters into the input buffer\\ using bash to expand a newline character\\ ([[http://lists.gnu.org/archive/html/screen-users/2007-06/msg00012.html|from here]]) | <code bash>screen -S <name> [-p <page>] -X stuff $'quit\r'</code> |
+A full example:
+<code bash>
+# run bash within screen
+screen -AmdS bash_shell bash
+# run top within that bash session
+screen -S bash_shell -p 0 -X stuff $'top\r'
+# ... some time later
+# stuff 'q' to tell top to quit
+screen -S bash_shell -X stuff 'q'
+# stuff 'exit\n' to exit bash session
+screen -S bash_shell -X stuff $'exit\r'
+</code>

+| enter screen command        | ''[[commands:colon|C-a :]]'' |
+| enable logging in the screen session | ''[[commands:logging|C-a H]]'' |
+===== Scrollback-buffer =====
+In copy mode, one can navigate the scrollback buffer in various ways:
+| half page up | C-u |           | half page down | C-d |
+| back | C-b |                   | forward | C-f |
+| cursor left/down/up/right | h/j/k/l |
