The link which I will post is for Braille Reference, an Apple application
which offers quick access to Standard English Braille, Computer Braille, and
Nemeth Code Braille. For those among us whe are not familiar with one or
more of these Braille codes or have forgotten what we did know is's ideal
and only costs 99 cents. There was a standard warning about downloading but
I didn't have any problems with it and have used my copy twice already.
