Scroll bar for computer display
View Patent ↗An improved scroll bar arrangement for a window (canvas) displayed on a computer screen includes a computer display canvas comprised of a wire frame and a scroll button (fader cap) at a side edge and/or bottom edge of the canvas. The fader cap is a rectangular box having a transparent center, so that onscreen objects behind the canvas are visualizable therethrough. The fader cap may be dragged along its respective side of the canvas to move the document through the canvas in typical scrolling fashion. The position of the fader cap along its edge is related to a ratio of the position of the portion of the document being displayed, to the total length (or width) of the document. Navigation aids include marker bars and lassoing marker bars to select document portions therebetween.
