THE MESSAGE LINE

Screen displays informational messages and other diagnostics in a
       message line.  While this line is distributed to appear at the
       bottom of the screen, it can be defined to appear at the top of
       the screen during compilation.  If your terminal has a status
       line defined in its termcap, screen will use this for displaying
       its messages, otherwise a line of the current screen will be
       temporarily overwritten and output will be momentarily
       interrupted. The message line is automatically removed after a
       few seconds delay, but it can also be removed early (on terminals
       without a status line) by beginning to type.

       The message line facility can be used by an application running
       in the current window by means of the ANSI Privacy message
       control sequence.  For instance, from within the shell, try
       something like:

              echo '<esc>^Hello world from window '$WINDOW'<esc>\\'

       where '<esc>' is an escape, '^' is a literal up-arrow, and '\\'
       turns into a single backslash.
