Hi all.

I do a lot of reading and writing of .brf’s directly from the display, either 
music or my own brand of literary Braille which is at about grade seven these 
days. The dot 456 combination is always tricky since it gets represented in 
computer Braille for embossing as an underscore, but received wisdom seems to 
be that underscore should get dot 7 added to it for refreshable Braille. On the 
Mac it was particularly annoying because if you forget and just hit dot456, you 
end up entering a delete character, as I’m sure others have found out to their 
cost. Anyway, this morning I had enough and tracked down the US 8 dot Braille 
table, which I’d always assumed would be embedded in a Duxbury .btb file. As it 
happens it’s just a plain plist in 
/System/Library/ScreenReader/BrailleTables/Duxbury.brailletable/Contents/Resources.
 After swapping the entries for 456 and 4567, I can now directly enter an 
underscore with 456 and so can write brf files in my editor of choice.

Other people might have already discovered this, but as it’s a fix for what a 
Braille nerd like me found an annoying quirk, I thought I’d report my success 
with it anyway.

Cheers.
Ben
