        A context manager for :func:`tty.setraw`.

        Although both :meth:`break` and :meth:`raw` modes allow each keystroke
        to be read immediately after it is pressed, Raw mode disables
        processing of input and output.

        In cbreak mode, special input characters such as ``^C`` or ``^S`` are
        interpreted by the terminal driver and excluded from the stdin stream.
        In raw mode these values are receive by the :meth:`inkey` method.

        Because output processing is not done, the newline ``'\n'`` is not
        enough, you must also print carriage return to ensure that the cursor
        is returned to the first column::
