Video Transcript in Storyline

Hello,

I'm experimenting with the (new to me) video transcript option in Storyline, and I have 2 questions: 

1. What is the name that is announced for the button? In testing it (with JAWS active) I believe the button only says "open" (or at least that is all I hear, and I do not have JAWS set to read very quickly... but I wonder if that is what others encounter.
2. Has anyone tried to have a screen reader read the transcript? I am trying and finding it to not be a great experience. It sound like its formatted like a list? 
   1. Sub question: I see that it's possible to remove the timestamps, is this something that can be programmatically set (like a player setting) or is it always on by default? I think not having it might make reading the transcript (with a screenreader) a bit easier. 

Thanks!
