Could LaTeX and ASCII Math be speech navigation options?

An Orca user wants to navigate in MathML content rendered in LaTeX and/or ASCII Math.

I realize that I can obtain the LaTeX/ASCII Math from MathCAT. Orca already supports those options for braille and for copying. The reasons why I'm requesting this as a MathCAT navigation option are:

* Orca's MathCAT implementation turns navigation in MathML expressions completely over to MathCAT, treating those expressions as black boxes. Being able to do so fills me with joy. 😄 I don't want to move away from that. But even if I were ok with it:
* Unlike other screen readers, Orca does not have a virtual buffer or any notion of virtual objects. The user is always in the actual document. The user's location is always a valid/real AT-SPI accessible object with a valid character offset. If I need to do this on my end, I'll need to create some sort of virtual object and take navigation over from MathCAT.

So... Any possibility of this happening on your end? (Please and thank you in advance.)

The issue names no files, tests, or specific entry points. Start by tracing MathCAT's MathML navigation handling and comparing it with the existing LaTeX and ASCII Math paths used for braille and copying; done means those representations can be used as speech navigation options while Orca continues delegating expression navigation to MathCAT.
