Help for using MS Office programmes is usually not accessible. And most accessibility content is aimed at apparently nondisabled users who work for people with disabilities. Freely available accessible content for people with disabilities has been fragmented or outdated. There has been no accessible, up-to-date and detailed guide to the programme. This book has been written for people who cannot use a mouse (especially blind and partially sighted people) to give them a solid introduction to MS Word and its most notable features.
