Scrolls the page to the left by a given number of pixels. The step takes one optional parameter: the pixel amount. When no number is supplied, the page scrolls left by the default of 350 pixels. The movement is relative to the current horizontal position, so it is the natural counterpart to scrolling right: scroll right to reveal content, then scroll left to come back.
The step operates on the page-level scrollbar only. If you are already at the far left, the step is a no-op: the browser clamps the position at zero, so it never fails. To jump straight back to the horizontal origin in one step, use the scroll-to-start step instead of repeated left scrolls.
