Document titles in header/footer?

When compiling on iOS, I see how to include page number and page count in the header/footer. What other variables can be included? Specifically, can I include the title of the current folder and/or document?

Everything you can do is documented in the sample appearance that is provided when tapping the help button alongside the Done button, when editing your appearance file. This help file is a fully functional appearance file that basically has most of it commented out as a reference. So it can serve as a starting point for your own setup.
