1. A method of operation of an electronic device system comprising:

  • detecting a drag performed on a touch screen, the drag having a first direction from a starting point and an ending point;

    detecting a stretchable cursor extendable based on the drag, the stretchable cursor having a cursor length, a cursor direction, a starting portion, and an ending portion at the ending point and larger than the starting portion at the starting point;

    displaying the stretchable cursor on the touch screen, the stretchable cursor stretched across a centerline on the touch screen;

    detecting whether a second direction of the drag is opposite the first direction;

    moving a starting position of the stretchable cursor toward the centerline and away from the starting point when the second direction is opposite the first direction;

    detecting whether the starting position reaches the centerline; and

    fixing a position of the starting position to a current position of the centerline when the starting position reaches the centerline.
