$ PEEK /DISALLOW

   This subcommand performs the following functions:

    1.  Lets no other non-privileged users watch your terminal by
        revoking all permission to watch granted through previous
        PEEK/ALLOW commands.

    2.  Any user currently watching with PEEK is forced to stop watching.

    3.  If any hot-keys were defined with a previous PEEK/ALLOW
        command (as displayed by $ PEEK/SHOW KEYS), then these hot-key
        defintions may also be erased, depending on the /KEYS_ERASE
        value currently in effect.

   Format:
        $ PEEK/DISALLOW          $ PEEK
                                 PEEK> DISALLOW
