How do I make a form button with a tooltip visible to a reader?
I’m preparing PDFs of old scientific literature, much of it taxonomic, and therefore densely populated with names of species, genera, geographic places, etc.
Over time, many of these names have changed. I want to use the Tooltip function to add a note to names that have been changed. I have no problem creating the tooltips — the problem is how to let a reader know that a tooltip is linked to text!
The tooltip button has to be transparent in order to display the underlying text; the problem is that because it’s transparent, a reader cannot know that there IS a tooltip attached to the text.
In the Mac program PDF Expert there is an option to highlight form fields, so all text blocks that have tooltips attached are immediately obvious; however, I cannot find any similar option in Acrobat DC. One doesn't want to waste a reader's time by asking them to run the mouse over all the text just in case there is a hidden tooltip!
And is there any way to eliminate the slight delay that Acrobat imposes before a tooltip is shown? It would be nice if the display could be made immediate on a mouse rollover.
Any suggestions?
Thanks!
