Disclosed is a portable communication terminal device and a method of displaying characters and picture for enabling every user to swiftly and correctly input desired characters or correct input characters. This is achieved by way of implementing the following: When the inventive portable communication terminal device has entered into a character inputting mode, of those functional operations including shifting of cursor in all directions on a display screen and another operation to effect selection, i.e., an entering operation, shifting of cursor in the vertical direction via a jog dial is provisionally allocated to the shifting of cursor on word (or phrase) candidate lists and also to the instruction for selecting the corresponding candidates. When the designated candidate lists are closed, shifting movement of the cursor in all directions and the entering operation are allocated to the character-inputting screen.

DETAILED DESCRIPTION The present invention has been consummated to fully solve the above problems.
The present invention provides a novel portable communication device and a novel method of displaying an image screen for enabling an operator to swiftly and securely input or correct characters without switching display screen even when there is merely a single operating device for shifting cursor.
The present invention also provides a novel portable communication terminal device and a novel method of displaying an image screen for freeing every user from erroneously operating the operating device by way of precisely coordinating the relationship between the direction of shifting cursor on the display screen and function of the operating device on the portable communication terminal device.
Such a novel portable communication terminal device is achieved by the present invention providing a portable communication terminal device which has a first cursor shifting device for shifting a cursor in a first direction on a display screen; a second cursor shifting device for shifting the cursor in a second direction on the display screen, wherein an editing object designated by the cursor on the display screen is selected via a specific operation performed through the first cursor shifting device; wherein, during a character input mode, the portable communication terminal device comprises: display means for displaying a predetermined candidate list on the display screen in response to the input of "kana" characters; first allocating means for allocating the first cursor shifting device to execute such operations required for shifting the cursor and selecting the editing object on the candidate list; and second allocating means for allocating the second cursor shifting device for shifting the cursor in the character input screen on the display screen.
The inventive portable communication terminal device functions itself in order to shift the cursor and select the editing object without switching display screen by applying such means for allocating the first cursor shifting device to execute an operation for shifting the cursor and selecting the editing object on the candidate list as well as for allocating the second cursor shifting device to execute an operation for shifting the cursor in the character input screen on the display screen
