Help - Is there a way to Return to the Table of Contents

[timezone]

We really need the ability to return to the table of contents when reading PDF technical or reference books.

Especially with PDF's it is very difficult to maneuver around without having the ability to move back to the table of contents. A few times I ended up at the beginning and had to login all over again. I might be in a 200 or 300 page technical book. I can jump very easily to a topic I want to read but when I want to move to another location I need to get back to the table of contents. Having this ability will allow one to quickly navigate the book. Otherwise why have the link to move to a location when you can't move back.

I thought either the up button or up arrow also allowed one to navigate back through the links. Am I doing something wrong or does this not work with PDF's?

Is it possible to return to the table of contents in a PDF file? Thank you

I discovered the small arrows on the bottom are the symbols that retrace the steps. If I am jumping between the table of contents to a location then I am only one step away from returning to it. I am much happier now. I also discovered that if the book is only displaying bars rather than numbers because there are too many pages I can swipe the area where the vertical bars are located to view the local page numbers. It is unfortunate retracing steps require the stylus but better than nothing. Now the technical book is usable.

On another note rather than jumping to a location in the book from the table of contents instead on occasion the keyboard or part of the keyboard displays.
