CONSTITUTION:A keyboard 4 contains four window selection keys 41 for selection of window in addition to a key 42 used for input of various data. Then the control key for a key 42 and an 'A' key are operated by a left hand, for example, on the keyboard 4 to call the menus. At the same time, the keys 41b and 41c (41a and 41d) of the keys 41 are operated by a right hand to select the menus. Then a menu is decided when the left hand is released form the keys. A window 35 to be changed is moved with use of a control key and the keys 41 of the keyboard 4.
