An apparatus for displaying a data stored in a memory on a display panel, such as a cathode ray tube in a scroll mode in which the data is scrolled on the display panel at a rate dependent on a renewal speed of a read out address of the memory, and is provided with manually rotatable dial means for generating a control signal for controlling the renewal speed of the read out address of the memory and therefore the scroll speed of the data, the control signal being dependent on the rotation of the manually rotatable dial, that is, rotational angle or rotational speed of the dial. Further, in an editing apparatus to which this invention is applied, the manually rotatable dial concurrently controls the tape transport speed of the video tape recorders, the video signals reproduced from the video tape recorders being edited.
