Re: [orca-list] A web-based accessible graphing calculator. Hurray!

[Peter Vágner <pvagner pvagner tk>]

Hello,

This looks like a very accessible web app.
It's a great way on how to experience orca's MathML support I guess.

This calculator has so called expressions list. When I type an 
expression into one of the entries the expression is evaluated and orca 
reads it in full.
Also as I'm pressing home and end keys it's reporting start / end of the 
expression. Is there a way to read such a MathML expression by members?
For example just to test how this is working I have came up with a 
random expression like this
\frac{3}{4}\cdot\frac{1}{2}

When I navigate over the entry field in Firefox 62 by character (using 
left and right arrow keys) current fraction is often presented twice. 
Also the fraction is announced in full when I navigate to it however the 
bottom denominator does not appear to be reported to me. Orca just says 
after start fraction and then the whole fraction when navigating left to 
right and it is not reporting the bottom part of the fraction when 
navigating right to left.

Please excuse me for a dumb question. This is all very new to me so 
perhaps I first need to learn it properly. Still if you can I would 
appreciate some hints.


Greetings

Peter
