I am trying to help a student send an email using his Refreshbraille 18 and the Mail app on his iPad. We can't seem to figure out how to input an underscore in the email address. I set it for Containers and 8 dot braille input. Do you know what dots should be pressed to create the underscore? Dots 4-5-6 don't seem to work. I couldn't find any other help online and thought you might have an answer.
Thank you so much if you can offer any help!
