Jana Scroeder has organised a zoom meeting to discuss online resources for blind programmers. It will be on Saturday 27 March, from 2 to 3:30 US Eastern Daylight Time. All interested people are invited to participate. I'll be there. I look forward to hearing their experience, problems and successes.

The zoom link and other information is at 

A math formula has a tree structure, as does the source code for a computer program. There's a shared interest in navigating complex trees. Particularly the blind math people who prefer to read math via the LaTeX source file.

with best regards
