"Hence one has to ask what happens existentially when I press a key. What happens when I press a typewriter key, a piano key, a button on a television set or on a telephone. What happens when the President of the United States presses the red button or the photographer the camera button. I choose a key, I decide on a key. I decide on a particular letter of the alphabet in the case of a typewriter, on a particular note in the case of a piano, on a particular channel in the case of a television set, or on a particular telephone number. The President decides on a war, the photographer on a picture. Fingertips are organs of choice, of decision." Flusser
