Creating a VoiceOver-friendly interactive text file or word document

Hello All, I'm trying to do something that I'm not sure is possible, and through googling, I couldn't find an answer to this, so I thought I'd see if any of you might know a solution. I have a fairly large Microsoft Word Document. It has various sections or "headings", and subheadings underneath those. for example: Main Heading: Dining: Subheadings: restaurants Snack Locations Coffee etc. If I were to mark this document with heading levels (heading level 1, 2, etc.) and I use the roader in VoiceOver to navigate through the headings, I still have to go through every heading, regardless of it's level, to get to what I want. So essentially, I want either 1 of 2 things: 1. An app that I could create (or something similar to that) where all of the main categories or headings could be displayed, and double tapping on an item in this main list would bring up it's sub-items, with a back button to return to the main list. Preferrably, more then one sublist could be created. or 2. somehow accomplish the same task above within a text file (the notes app, an e-mail, etc.) by telling voiceover what heading level I wanted to look through, and then going to that heading's sub level. I know nothing about coding, and I hope this all makes sense in some way. If anyone is unclear about what I'm saying or what I'm trying to do, please let me know. :) Any help is greatly appreciated. Thanks so much, Rocco
