what is computer braille?
Computer Braille is not grade one, it is Ascii Braille (American Standard Code for Information Interchange braille). In computer braille, you can not type contracted braille. The symbols are what are contractions in grade two. Example: TH-chord in grade two is the question mark (?) in computer braille. For the list of Computer Braille symbols, see: the type text section of the Icon and Braille Plus user’s guide.
