Good day, Contexters
I've been using plain TeX for many years (EmTeX, if anyone can remember that, and latterly XeTeX), but my motivation for getting acquainted with ConText, rather late in life, is the need to produce tagged PDFs that will be accessible to the visually impaired (generally using an audio reader), and I understand (or at least hope) that ConText can help with that.
I'm only just getting started with the Not so Short Introduction, and of course have many questions which I think/hope I will be able to answer myself from the documentation: I've not managed to load pstricks or edmac, for example, but this must be possible, and some primitives such as \baselineskip seem to have disappeared, together with the font-call system I'm used to:
\font\umirtenpointsevenfive
= "MinionPro-Regular:+onum:mapping=tex-text:letterspace=1.6" at
10.75pt
All that will come as I read the instructions, but what I'm most interested to achieve is tagging that will not only produce the usual column of bookmarks at the left-hand side but will also allow an audio reader to read such things as alt-text for illustrations and, crucially, read a heavily footnoted text in the correct order. For this I take it that the footnotes will have to be tagged in a special way, allowing visually impaired readers either to suppress them as the text is read out, or else to include them at the point where the cue occurs, then revert back to the main text. With my XeTeX-produced PDFs an audio reader will simply read all of the main text on a page, then the footnotes (the last of which may be split between pages), and then start again on the next page - clearly annoying and unacceptable to those who can't see the PDF.
I'd be most grateful to be pointed in the right direction - or is what I've outlined simply not achievable?
