Abstract
A system and method for enabling a user to input characters using a directional pad of a computing device. The directional pad is configured to generate directional inputs. The invention creates mappings for the directional inputs where each of the mappings associates at least one of the directional inputs with at least one of the characters. The user may activate one of the mappings by selecting one of the directional inputs. While the mapping is activated, the user may input a character by selecting a directional input associated with that character.
