Great research on your part.

Just for interest I took the following from an article from adobe. It is talking about the [change accessability reading options] screen found under the document menu.

"Use the third screen to choose the reading order for documents that
are not tagged. The following options are supported:
Infer Reading Order From Document (Recommended). When this option is selected, Adobe
*
Reader determines the reading order of untagged documents using an advanced method of layout analysis. This option is recommended because it is most likely to provide the most accurate results. It does, however, require more analysis and therefore may be slower than the other two options.
Left-To-Right, Top-To-Bottom Reading Order. When this option is selected,
*
Adobe Reader interprets the reading order of untagged documents starting
from left to right on the page and moving from top to bottom.
Use Reading Order In Raw Print Stream. When this option is selected, Adobe Reader
*
interprets the reading order of untagged documents based on the raw code in the PDF document - essentially, the order text was recorded in the print stream. When you choose either of the last two options, Adobe Reader does not include
form fields in the content, and it does not recognize tables.
Depending on the complexity of the PDF document, on-the-fly tagging may not adequately capture the intended reading order of the document. Many PDF documents have multiple columns or complex page designs that can affect how well Adobe Reader interprets the content. If you are having trouble reading a particular PDF document, you can experiment with the various Reading Order options to see if one works better than the others. The next control on this screen is a check box labeled "Override the Reading Order in Tagged Documents." While the Reading Order options above apply to untagged documents by default, this option causes Adobe Reader to use the reading order you selected (instead of using the reading order specified by the tag structure) for tagged documents as well. This option is useful if you receive PDF documents that are poorly tagged. The final control on this screen is a check box labeled "Confirm before Adding Tags to Document." When you select this option, Adobe Reader asks you to confirm its tagging options before it prepares an untagged document for reading by your assistive technology. Tagging can be a time-consuming procedure, particularly in larger documents, and this option alerts screen reader users when that procedure is about to begin."

I hope this is of some use.

Hi there,
I have seen this over and over. There are small boxes sometimes, not in story books, but rather in theory books (such as the books in the For Dummies series (E.G. programming in C++ for dummies, ASP.net for dummies) and the Idiot's Guide to whatever books) that make a line break up. Let me paste a bit of a book called the Complete Idiot's guide to Yoga that I found lying around. See?

As you see, lines seem to get cut off, and you seem to have two things talked about in one line. Is there a way to split these two, such as a table-like structure one could navigate?
Thanks!
