Focus Order

I am working with Focus Order and using the Tab key. When entering text in a text field and then pressing Tab, the next slide displays a yellow border around it. I have followed the information to remove focus by deleting the object and/or moving it to the end of the order without any change. I have also right-clicked on the object > Accessibility and deselected the Object is visible to accessibility tools check box.  I am using version 3.68.28887.0 with a Chrome browser.

Thank you. Maria Daley
