Abstract:
1. A mobile communication terminal, comprising: an input unit including a plurality of input keys, wherein the plurality of input keys include up, down, left, and right direction keys; a calculator calculating an interval between a consecutive selection of one of the direction; and a processor storing information corresponding to a state of the mobile terminal prior to one of the direction keys being selected, and executing a predetermined function corresponding to the consecutive selection of one of the direction keys if the calculated interval is within a threshold time, wherein said predetermined function is different from a function associated with a single selection of a corresponding one of the direction keys, wherein the predetermined function includes a different predetermined function for each of the direction keys that is allocated based on an intuition, wherein continuous selection of the up direction key within the threshold time causes the processor to display a menu that is a higher level menu than a currently displayed menu., continuous selection of the down direction key within the threshold time causes the processor to display a menu that is a lower level menu than the currently displayed menu, and wherein continuous selection of the right direction key within the threshold time causes the processor to store currently displayed data, and continuous selection of the left direction key within the threshold time causes the processor to delete currently displayed data.
