Abstract: Systems and methods for gesture repetition that is easy to repeat quickly. A user is able to quickly repeat any activation of a key, including any of the alternate, overloaded functions that are associated with the key. In addition, by appropriately defining the gesture, a large number of these repetitions can be quickly generated. These repeated activations can be generated much faster than a key can be repeatedly tapped with sufficient accuracy, and far faster than an alternative function can be repeatedly generated when each repetition would require again waiting past an initial time threshold. Furthermore, the number of repetitions can be easily and precisely controlled by the user. As the desired number of repetitions is approached, the user simply begins to repeat the gesture at a slower pace until precisely the desired number of repetitions is achieved.
