ABSTRACT:
A portable device includes a display unit, a memory, input keys, and a microprocessor. The display unit has a character window, which includes a selecting character window and a selected character window, for displaying characters. One character line including the character which has virtual coordinates indicated by a cursor is displayed in the selecting character window, and the character selected from the characters in the selecting character window is displayed in the selected character window by input keys. The memory stores the characters having intrinsic virtual coordinates, and several input keys serve for navigating across the characters by using the virtual coordinates of the characters to select the characters. The microprocessor controls the display of the characters on the display unit in correspondence to the input of the input keys.
