Re: Untagged PDF doc with table structure

I am not 100% sure that is true Karen. There is an additional pane in
Acrobat called the Contents pane. I consider this to hold the guts of the
PDF, or the content. It sounds like whatever software was used to make the
PDF used structure, but didn't create tags. So if Lynn opened up that pane,
I bet she'd see Container <Table> ....., and so on, then JAWS is making the
connection you mentioned, which appears to "read normally." If we then use
"add tags" option, the added tags should roughly mimic the structure from
the contents pane.

Then it will often show you the tagged choice. I'm not clear why this is,
but it happens often enough that I pretty much always escape from the
initial screen

There is an additional setting that needs to be set. You must open the
pages pane, select all pages, choose properties. By default this is set to
unstructured, this is like saying "guess what to do." The other options are
like use tags, use the document language to pick (left to right), and one
more that i am drawing a blank on
