Want to Use Tab as a Shortcut Key in HTML 5

[abigailatssc]

Is there any way to do this? We're replicating software where the Tab key is used HEAVILY. We published in SWF until now, but we'll be moving to HTML5. We are using Captivate 9, but will likely move to Captivate 2019 at some point.

I tried Lilybiri's solution shown here, but it didn't work:

I want the Tab key to work as a "go to next slide" for Captivate 8

Does anyone have any suggestions for this?

How did you test?

I added the button to the master slide, but made it visible, so I could see that is was actually there. Then I published to HTML5, unzipped, and made my way to the slide. Tab doesn't activate the button, it just moves focus to the playbar.
