Identifying a Selection String

We are creating a large curriculum in  areas of medicine.  We would like the student to be able to consult an existing data base of drugs with their chemical composition, side effects, dosage etc.

We can add a button on all the slides which when clicked will open another browser window and take the user to the data base.  However, we would like to be a little more elegant than that.

Specifically we would like the student to be able to select a drug by selecting the name of the drug out of the text on the slide.  With her mouse she would select the drug name and then click on the button and the new browser window would open but it would already have searched for the drug name and then  the content on the particular drug  would display to the student when the window opened.

We could do this easily IF WE HAD A WAY OF OBTAINING THE SELECTED TEXT STRING.  We can then pass this through the url and make the right search.  So my question is in Storyline 360, when a student selects text on a slide, how can I get the string of the selected text?

Someone before me must have wanted to do something like this and if anyone knows how, I would appreciate it.
