I am having real difficulty adding alternative text tags. I created an INDD doc with rollover buttons linked to URLs firstly in InDesign CS4. I couldn't add alt text tags in CS4 so I then tried to add them in Acrobat X Pro but failed. Acrobat keeps wanting to class the PDF as a form. I then installed InDesign CS6 from the cloud and added alt text to the rollover buttons via object export options. However, these do not show when I export to PDF.
Can someone help me add alt text to my rollover buttons in my interactive PDF either in InDesign CS6 or in Acrobat Pro after I export it?
Many thanks indeed
