Re: Converting simple math to Mathtype: Scope

There is some support of MathML out there. JAWS certainly supports it for
both speech and braille and has a test page available. I believe Sina has
created an equivalent plugin for MathML on NVDA. I don't know directly
about Window Eyes, but could test later today. Also, on the Macintosh
front, if your VoiceOver WEB mode is "DOM" then Math ML support is almost
as good (via voice, I haven't tested Braille) as with JAWS. If WEB mode for
VoiceOVer is set to grouping then MathML drops a bit of the context. Also,
I have noticed issues that I have not yet resolved with JAWS and it
occasionally seeing operators in MathML equations as different characters.
