[orca-list] reading objects letter by letter in firefox

[Michał Zegan <webczat_200 poczta onet pl>]

Hello.

I came across the following problem: there are some lectures on the 
internet about maths, and those lectures contain graphics. However, 
those graphics have alternative descriptions that is latex code. The 
problem here is that I cannot carefully read this latex code as orca 
presents this graphic object as a single thing and you cannot actually 
navigate through letters of the code on the alt text.
Is there any possibility to add such a feature?
