On May 18 2013, NVAccess is pleased to announce the final 2013.1 version of NVDA.
Highlights of this release include a more intuitive and consistent laptop keyboard layout; basic support for Microsoft PowerPoint; support for long descriptions in web browsers; and support for input of computer braille for braille displays which have a braille keyboard.
NVDA is used by 10s of thousands of blind and vision impaired people spanning more than 120 countries, enabling them to socialize, get an education, and participate in the workforce — things that may not have been possible previously for those who could not afford other expensive screen reading solutions.
