The program collects statistics based on your previous 5 key-presses. That's one way to do it, but there's a much better, extremely elegant algorithm for quickly making predictions by averaging over a doubly exponential number of models of this form. The algorithm is called Context Tree Weighting, or CTW for shorts. Look it up.
