By Rick Fox, 5 April, 2015 Forum Braille on Apple Products When I'm using the Braille onscreen keyboard, dot 4 sometimes results in "dot 4" and sometimes "@". I'm not sure how to produce the @ sign with certainty when I want it. Any suggestions? Thanks. Options Log in or register to post comments Comments What code are you using? Which braille code are you using? In UEB, dot 4 followed by dot 1 is the 'at' sign. I believe iOS defaults to UEB for many locales, but go to Settings > General > Accessibility > VoiceOver > Braille to check which code is in use.
