If you want to draw attention to certain areas in your PDF file when the user hovers with the mouse above them, this is the ideal tool to achieve that.
What this tool will do is add special cross highlights to the file that will show up in bright yellow when the user hovers with the mouse above the areas you define.

All you have to do is create form fields with the names "HotSpot1", "HotSpot2", "HotSpot3", etc., in your file, like so:

It's as simple as that... Just save the file, and you're done.
