Key bindings for screen command

Key bindings

screen commands consist of a command character (Ctrl-a by default) followed by another character. For many of the commands, you can also specify the character as Ctrl-character–e.g., Ctrl-a Ctrl-d as well as Ctrl-a d. The default key bindings are listed here. You can change the bindings for yourself in the $HOME/.screenrc configuration file, or for all users in /etc/screenrc. The term in parentheses that follows the description is the equivalent configuration-file command for changing the key binding.
