Is it possible to add rollover text in PDF generated from FM11?

Hi

I am creating a documentation using FM11. In this, I have used quite a few terms. Though I have given their definitions as a separate section within the FM file, I also want the definitions to be available a rollover text. Is that possible? For example, when the learner moves his mouse over a term called "Project folder", a tooltip-like text should appear with the description of "Project folder".

If not, can I give the description as a pop-up window that will work in PDF?

Worst case scenario, I will have to go with "Jump to Named Destination" feature in FM to take the learner to description section and ask him to use "Previous View" (in PDF) to get back to the position where he came from.

P.S.: I have read that Shlomo Peret's Timesavers can do the job for me. But, for now, I am not looking to buy anything.
