help needed in reading old ffs

Hi all, I want to read some old ffs but the writer has put page numbers instead of links to the chapters in the ibdex. 

The earlier format had the page search option so it was easy to jump to the page. But now I don't see the page search option, and it is tedious to keep on pressing next page to reach the required one. 

How are you coping with this problem? Any ideas?

Thanks

We can still jump page ... see above on page number ( 1 of Go ) ... edit ( which page you want to go )  and click to Go

Thank you. You are a lifesaver 😊
