Magic Keyboard

In the movie, when K is (I think completing the sign up procces for J), There

is a shot that shows a 3/4 view of his back while he is typing and J is in

the forground.

If you look at his hands (K's) you will see that his hands are not touching

the keyboard but you will hear a typing noise anyway. This is so that the

text that the film makers wanted would appear on the screen.

This technique has also been used in other movies where a actor has to type

fast and get the desired text onto the computer screen.
