Is there a way to add "alt text" to links in PDFs in Adobe Acrobat?

In Adobe Acrobat Pro, it's not that difficult to add links to a page, but I'm wondering if there's also a way to add "alt text" (sometimes called "title text") to links as well. In HTML, this would be done as such:

<a href="url" title="Text goes here">link</a>

Then when the mouse is hovering over the link, the text appears as a little tooltip. Is there an equivalent for PDFs? And if so, how do you add it?

Solution

  • Actually PDF does support alternate text. It's part of Logical Structure documented PDF Reference 1.7 section 10.8.2 "Alternate Descriptions"
