There is a company in southern Arizona that does training for this sort of thing. I don't know if they specifically work with the program you are using, but I will email my Voc Rehab team and find out the contact info for the company. They do remote training for visually impaired people.
Edit: I found a sylibus from the workshot that they were part of.
$1 I've never worked with them, but they seem to specialize in training visually impaired people to use technology. Contact them and see if this is something that they can help with.
Also, I have no idea what kind of cost would be associated with their training.
