Word: Productivity/Accessibility Tab
The Texas Governor's Committee on People with Disabilities worked with a multi-agency team of accessibility professionals to create several "modules" on how to create accessible Microsoft Office documents. They also created a Microsoft Word ribbon "Productivity/Accessibility tab" that works in Word versions 2013 and 2016 to make it easier to create accessible documents by placing all the commands in one place. The download is available along with the instructions for installation.
