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 (SeeInvoking 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.
