Set the command character to x and the character generating a literal command character (by triggering the
to y (similar to the ‘-e’ option).
Each argument is either a single character, a two-character
sequence of the form ‘^x’ (meaning C-x), a backslash followed
by an octal number (specifying the ASCII code of the character), or a
backslash followed by a second character, such as ‘\^’ or
‘\\’. The default is ‘^Aa’, but ‘``’ is recommended by
one of the authors.
Set the default command characters. This is equivalent to the command
escape except that it is useful for multiuser sessions only.
In a multiuser session
escape changes the command character of the calling user, where
defescape changes the default command characters for users that
will be added later.
Send the command character (C-a) to the process in the current window. The keystroke for this command is the second parameter to the ‘-e’ command line switch (see Invoking Screen), or the
escape .screenrc directive.
This command has the same effect as typing the screen escape character (C-a). It is probably only useful for key bindings. If the ‘-c’ option is given, select the specified command class. See Bind, See Bindkey.
