            [GREG1\]LOOK "Command"

        Calls  the  cursor,  and  executes the specified command each time it is
        pressed. The command can be a procedure (e.g. @my_look) and can test the
        pressed  character  which  is added at the end as first argument.  Usual
        exit keys ("E", right-clic, ...) or "*" can be used to exit.  For  exam-
        ple, a calling session may look like:
                GREG-PROMPT> LOOK "SAY You pressed "
                You pressed Q
                GREG-PROMPT>
        if "Q" and then "E" have been pressed.
