plokta
     
        /plok't*/ Press Lots Of Keys To Abort.  To press random keys
        in an attempt to get some response from the system.  One might
        plokta when the abort procedure for a program is not known, or
        when trying to figure out if the system is just sluggish or
        really hung.  Plokta can also be used while trying to figure
        out any unknown key sequence for a particular operation.
        Someone going into "plokta mode" usually places both hands
        flat on the keyboard and mashes them down, hoping for some
        useful response.
     
        A slightly more directed form of plokta can often be seen in
        mail messages or {Usenet} articles from new users - the text
        might end with
     
               ^X^C
               q
               quit
               :q
               ^C
               end
               x
               exit
               ZZ
               ^D
               ?
               help
     
        as the user vainly tries to find the right exit sequence, with
        the incorrect tries piling up at the end of the message.
