PROBLEM TO BE SOLVED: To achieve an excellent user interface in which a user never be confused. SOLUTION: A sort list made for group jump is made correspondent to group jump operation previously. Thereby, when group jump operation is performed, a group can be selected from the list made coincident to the operation, thereby, such a problem can be solved that group jump cannot be performed even if jump operation is performed. Consequently, occurrence of such situation can be prevented surely that the user is confused as a conventional case in which there are two cases of that group jump can be performed and that group jump cannot be performed even if jump operation is performed. Also, since group jump operation conforming to a list separate from a list for retrieving utilized by search can be performed by this constitution, the degree of freedom of group jump can be widened.
