SOLUTION: An information processor 100 comprises: a display section 130; an input section 120 having four direction keys for indicating each of horizontal and vertical directions; and a control section 110 for displaying a virtual board, which comprises a plurality of first blocks having no functions set thereto, arranged adjacently along at least one direction of horizontal and vertical directions, and a plurality of second blocks having functions, arranged adjacent to the first blocks, at a display section 140 along with a focus indicating a block being selected currently and for moving the focus according to a direction instruction signal supplied from an input section 120. The control section 110 executes functions when the functions have been set to the destination of the focus. COPYRIGHT: (C)2009,JPO&INPIT
