Mathematics in PDFs can be cumbersome for any purpose but reading or printing. In particular, copying mathematics in order to use it in another document, and screen-reading for visually impaired consumers.
Both issues can be solved using the accsup package; see
- here for copy-pasting (use
accsupto add detokenized math environment) and
- here for screen-reading (use
accsupto add a natural language version).
Since both solutions use the same mechanism, it is not clear how to achieve both at the same time, or if that is even possible.
Can we annotate formulae in PDFs so that they can be copy-pasted nicely and read by screen-reading software?
