FIELD: physics, computer engineering.
SUBSTANCE: invention relates to electronic devices. The device comprises a display subsystem, a logic subsystem and a data storage subsystem, operably connected to the display subsystem and the logic subsystem, wherein the data storage subsystem contains interface instructions executed by the logic subsystem so that, when a copy of a displayed object is placed in a predetermined region of an exchange buffer, the displayed object is visually changed to indicate that the visually changed copy is attached in the predetermined region of the exchange buffer and is therefore suitable for use in a copying procedure; when the copy is deleted from the predetermined region of the exchange buffer and placed at the required target location, the initial appearance of the displayed object is restored.
EFFECT: high rate of inputting information.
