        referred to as %%nn.  A job may also be referred to using a prefix of the
        name used to start it, or using a substring that appears in its command
-       line.   For  example,  %%ccee  refers  to  a  stopped ccee job.  If a prefix

                      the terminal's function keys.  The word on the right side
