\function{flush}
\synopsis{flush}
\usage{Void flush (String msg);}
\description
  The \var{flush} function behaves like \var{message} except that it immediately
  displays its argument \var{msg} as a message in the mini-buffer.  That is,
  it is not necessary to call \var{update} to see the message appear.

\function{tt_send}
\synopsis{tt_send}
\usage{Void tt_send (String s);}
\description
  This function may be used to send a string specified by \var{s} directly
  to the terminal with no interference by the editor.  One should
  exercise caution when using this routine since it may interfere with
  JED's screen management routines forcing one to redraw the screen.
  Nevertheless, it can serve a useful purpose.  For example, when run in
  an XTerm window, using
#v+
        tt_send ("\e[?9h");
#v-
  will enable sending mouse click information to JED encoded as
  keypresses.
