Horizonal Scrolling through pointer on scroll bar

Issue Type: <b>Feature Request</b> Often times when I have to scroll through lines, I have to hold Shift key and then scroll. I request to you include a scroll feature so that if the mouse pointer is on the horizontal scroll bar, while scrolling the scroll wheel, it will scroll horizontally.
