[BlindMath] Help with NVDA and MathML

Mon Jul 16 22:00:08 UTC 2018

Hi Everyone:

Last I had tried navigating MathJax rendered equations, I used Shift +
SpaceBar to open the MathJax menu. From there, I used the arrow keys to
navigate to the extension menu item and activate it. I had more success
using the MathJax A11y extension in Chrome.

HTH,
