Abstract
An image display apparatus has a manually operable inputting device such as a remote controller. A predetermined function, for example, as a picture-in-picture is allocated to a predetermined area of a screen of a CRT display. When a cursor is located in the predetermined area by a mouse remote controller and a setting key of the mouse remote controller is clicked, a CPU executes the function allocated to the predetermined area.
