Claim:
1. An electronic device comprising: a display portion that has a display screen; a plurality of operation keys arranged along with the display screen in a predetermined positional relationship with the display portion; and a display controller that controls a display such that, responsive to a certain state of the electronic device, information indicating the certain state is displayed on the display screen, wherein the display controller displays a dynamic figure on a region on the display screen corresponding to a position of a specific operation key to be operated at a time of the certain state, among the plurality of operation keys, the dynamic figure is a figure separating from the specific operation key while spreading around the specific operation key, or approaching the specific operation key while narrowing around the specific operation key to direct the user's attention to the specific operation key as an operative selection corresponding to the information indicating the certain state so that a user can easily recognize which key of operation keys to operate with reference to a pattern of the dynamic figure, wherein the display controller does not displays the dynamic figure when there is no specific operation key as an optative selection corresponding to the information indicating the certain state; and wherein a spreading or narrowing rate differs depending on a part of the dynamic figure such that the spreading rate of a part of the dynamic figure close to the specific operation key is higher than that of a part of the dynamic figure far from the specific operation key, or the narrowing rate of a part of the dynamic figured far from the specific operation key is higher than that of a part of the dynamic figure close to the specific operation key.
