Information processor 100 includes display 130, input part 120 which includes four direction keys for specifying up, down, left, and right directions respectively, and controller 110 which displays a virtual board and a focus indicating a currently selected block on display 140 and which moves the focus according to a direction indicator signal supplied from input part 120. The virtual board includes a plurality of first blocks, which are arranged contiguously along the up/down direction or the left/right direction or the up/down and left/right directions and to which no function has been set, and a plurality of second blocks which are arranged in proximity to the first blocks and to which a function has been previously set. If the focus is moved to any one of the plurality of second blocks, controller 110 executes the function which has been set in the second block that is a destination of the focus. |
