Abstract
Multidirectional keys of a reduced keypad are used to disambiguate between multiple symbols associated with a single key. For example, pressing a key identifies a collection of two or more symbols associated with the key and subsequently rocking the key selects one of the two or more symbols as unambiguously identified by the user.
