screen: Command Character
14.3 Command Character
======================
-- Command: escape xy
(none)
Set the command character to X and the character generating a
literal command character (by triggering the 'meta' command) 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.
-- Command: defescape xy
(none)
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.
-- Command: meta
('C-a a')
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 (Invoking Screen), or the
'escape' .screenrc directive.
-- Command: command [-c CLASS]
(none)
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.
Bind, Bindkey.
