Abstract
A keypad and method for arranging keys on a keypad is accomplished by a keypad typically including numeric keys imprinted with or adjacent uniquely assigned numerals ranging from zero through nine. The keys are arranged in a continuous, typically ascending, sequence residing in two parallel rows arranged horizontally, vertically or diagonally in a clockwise orientation (i.e. traversal of all the keys of both rows in sequential order is in a clockwise direction).
