        [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
    if "Q" and then "E" have been pressed.
