i can summarize it. duplicate the layer with the link a couple times. if it isnt already raterize the text. then go to filters>blur>motion blur and choose a flat angle, find a good distance, but not overkill. repeat but change the angle on each one. you should have just a flat one like --- and an up and down one like | and one or two diagonal ones, eg \ or / . optionally, you can move the text around a little on each one. then you go into imageready, and make 4 or more new frames. make the first layer visible on the first frame, then in the new frame make it invisible and hte next layer visible. repeat this till you have all your frames. it should look like its shaking.
