Claim:
1. An electronic device comprising: an integrated touchscreen panel touched by a user, comprising a display section for visually rendering an operation area that includes a reference area and a non-reference area; an informer informs the user of an operation status of the user; a controller controls an operation of the informer; and a distinguisher distinguishes between a first operation where the user searches for the reference area on the integrated touchscreen panel and a second operation which is a key input operation to the operation area, wherein the controller controls the operation of the informer based on a result of distinction by the distinguisher, wherein the controller disables key input to the operation area during the first operation; wherein, when key input to the operation area is disabled during the first operation and the controller determines that the user has continuously touched the reference area for a predetermined time or longer, the electronic device indicates a change in input mode through a visual, auditory or tactile sensation, the controller enables key input to both the reference area and the non-reference area after the touch on the reference area ceases based on the determination that the user has continuously touched the reference area for the predetermined time or longer and then ceased touching the reference area, so that key input to the operation area is no longer disabled; and wherein when key input to the operation area is disabled during the first operation and the controller determines that the user has not continuously touched the reference area, for the predetermined time or longer while key input is disabled, key input to the operation area remains disabled.
