// this uses the first of whichever is encountered:
// (A) the "jump to page" links at the top of lists, like on works/bookmarks listings, tag search results, etc
// (B) then the chapters in a work
// (C) and finally the works in a series
// meaning that if you're on chapter 1 of work #3 in a series, pressing the left-arrow key will take you to work #2 in the series
// if a work is in multiple series, it's not quite reliable because it will use the first one that shows up in the metadata
