If you’re using a text box to position text on the page, remember that you can do this with indent; this will look just as good, and won’t cause such problems to the Braille transcriber.
If you’re using the Text Box to mix graphics and text, it’s actually an image you’re making. How will the Braille reader access this information? Can it be rendered as a tactile diagram? Duxbury brings in text boxes, but at the point they are placed – which can cause confusion; make sure your Text Box is placed in the proper place in the text so that the information flows smoothly, and use some extra text to describe the graphical contents. You can include the descriptive text inside the Text Box, or – if you have to put the original text Box out of sequence – you can use another Text Box to refer to it by Figure number.
