The invention concerns a method for precise positioning of a marker (42) on a display. The method comprising the steps of (a) displaying a marker (42) overlaid on an image on a display, wherein the marker (42) indicates a first point (43); (b) obtaining the coordinates of a second point (44) on the display (5), in response to a user input event (64); (c) determining the coordinates of a third point (54) on the display (5), said third point (54) being located at a defined distance (52) from the first point (43) in a direction (48) defined by connecting the first and second points (43, 44); and (d) moving the marker (42) from the first point (43) to the third point (54), so that the marker (42) indicates the third point.
