I am using DITA to create .pdf files.
How do I make a 1-3 second highlight of text that I'm referring to with a link?
e.g. I click a link, which redirects to a phrase (picture, table, etc.), which is then highlighted for a few seconds.
AFAIK, this could work using <fo:multi-properties>, but this is not supported by any of the DITA-OT formatters (FOP, XEP, Antenna), see: 6.9 Dynamic Effects: Link and Multi Formatting Objects
