Cap 2017, new icon, want to remove action
Hello -
I have Captivate 2017, and I have found a new icon that I don't recognize. It is a small light blue square with small lines and an arrow pointing to the top right hand corner. It shows up only in Preview, and when clicked it makes the text on screen come up on a different background. I understand it to be some sort of way for the text to be larger and/or more contrast, however I would like to remove it for my project. How can I remove this action?
Thank you
