Thanks to Brian, Chris, and Madonna for your responses to my question
about how to create a google doc.
The cinstruction to type doc.new - did work in FireFox. Added was the
instruction to press enter on sign-in.
The AFB tutorial, ten modules in all, is helpful, but I could not find
where within the modules to "create a new document". The other topics
covered are quite thorough and helpful. I read the modules with NVDA
instead of using the MP3 files. Thanks again, problem resolved!
