ABSTRACT:
The present invention relates to a keyboard with a two-dimensional actuator for generating direction signals which can be used to move a cursor shown on a screen to a target position. The keyboard comprises an encoding circuit, a plurality of text keys connected to the encoding circuit each for generating a corresponding text signal, four direction keys connected to the encoding circuit each for generating a corresponding direction signal, and a two-dimensional actuator connected to the encoding circuit which can be actuated at least toward four predefined directions which are the same as the four predefined directions of the four direction keys. When the actuator is actuated toward any of the four predefined directions, the encoding circuit will generate the direction signals which are the same as the direction signals generated by the corresponding direction key.
