Shows position after scrolling (by line ↡, or by page ⇓) for better reading continuity.
When scrolling web pages it is often difficult to find the last
previously visible line to keep on reading.
This is most apparent when a scroll has less than a full page to go at the top or bottom of a document.
*Last Scroll* provides a visual hint where to keep on reading, and how we got here.
Click the visual hint to toggle its visibility.
