ABSTRACT:
In a data processing device having a display and a keyboard, a cursor on the display is moved with each of input keys on the keyboard in a predetermined processing mode designated by a mode change key. There are two ways for determining the directions to which the cursor is moved. One is that the directions is determined in accordance with a positinal relationship between two keys successively operated. The other is that the directions is determined in accordance with a positional relationship between the operated key and a reference key determined in advance. Thus, each of keys for respectively inputting codes are utilized as cursor movement keys.
