Move between textboxes using <Enter> instead of <Tab>

Hello Captivate Forum,

New to the forum and new user to Captivate here.  I am assisting in the development of a course that is designed to resemble a console application used to facilitate prescription orders.  The customer would naturally like it to 'act' as close as possible to the actual application.  In the actual application, the user hits <enter> to move from line to line on the screen.  In the course, we have created a series of TEB's to represent these lines where the user inputs commands.  To meet the goal of emulating the actual application, we would like to navigate the textboxes by using <enter> instead of <tab>.

What we have tried:

Setting the shortcut for the TEB to <enter> - this seems to work for built in actions such as continue, jump to slide, etc., but does not move focus to the next TEB

Using Execute JavaScript - window.document.getElementById("Textbox1").focus();

and

function moveFocus(){window.document.getElementById("Textbox1").focus()}; movefocus();

I looked through the common JS interface (cpAPIInterface) as well and did not see any specific built in method that supported what we are trying to do, but granted I am brand new to Captivate and new to JS as well.

The closest example I have been able to find was here - https://forums.adobe.com/message/126006#126006

Any help would be great!

Thanks!
