Use the Tab key after typing text and numbers in data fields

I need learners to use the Tab key after typing text and numbers in data fields without the yellow border appearing on slide objects, slide borders, and the video player.  As I am sure you realize, using the Tab key is a common way of navigating most software applications these days.  Pressing the Enter key, however, usually submits user data.

I have tried previous work arounds suggested in the forum.   Some date back more than 8 years ago. Unfortunately, I have not found a clear solution.

Since we are unable to completely disable accessibility features, is there any reason why Articulate has not introduced a lesser used key (not Tab) for this function?   I think that would be an easy fix for them and likely retain customers and create new ones.

Any suggestions on how to solve this would be greatly appreciated.

Thanks!
