[Blindmath] latex beginner questions

[Victorious]

Hi,

I've been contemplating learning LaTeX. The separation of content and
formatting sounds appealing especially for blind users.

1. Which distributions come with accessible editors for windows?
2. How do you deal with large tables, for e.g 8x10 cell tables? It is easy
to navigate by column or row and edit individual cells in a wysiwyg editor
like microsoft word. Is there a way to do this in latex, or is it not suited
for doing frequent modifications to large tables?
3. Are there accessible editors that allow you to switch quickly between
reading the source document and reading how the document is rendered?
4. Is there a way of avoiding enclosing all mathematical expressions with $
signs? It would be easier to read without the enclosing $ signs.
5. How difficult would it be to use latex for generating drawings? (for the
most part of trees and graphs).
6. Does anyone have any experience with lightweight markup languages like
AsciiDoc, and how they compare with LaTeX? Its goal seems to also be to
allow the writer to focus on the content.
