  , numpages: '#page_select' // css selector to get the number of pages. elements like (select, span, etc)
  , curpage: '#page_select' // css selector to get the current page. usually the same as numPages if it's a select element
  , nextchap: '#next_chap' // css selector to get the link to the next chapter
  , prevchap: '#prev_chap' // same as above except for previous
  , wait: 3000 // how many ms to wait before auto loading (to wait for elements to load), or a css selector to keep trying until it returns an elem
