Scroll text and Accessibility

Hi Katie, the redesigned accessibility functionality (the March 2020 update) where you can use both 'tabs and key arrows' is totally confusing for blind people. They would never know when to switch into arrows (I don't know this even though I'm not blind and can see the yellow selection box). All my colleagues (SL developers) don't like it.

Another thing is that it's buggy: E.g.: I have 5 interactive buttons on the slide. The tab recognises just the first one then when tab pressed again, it skips the other 4 buttons and go straight to the slide navigation. In that case I want to go back to this button using Shift+Tab but it selects the 5th interactive button (instead of the first one). Where is the logic here? 

Is it ANY WAY to switch into JUST TABS (no arrows) functionality like it was before just a couple of weeks ago? Can you imagine how many past courses would need to have instructions changed due to this update?

E.g.: I have 300 courses with instructions that explain to use just tabs to navigate. They were created 1 year ago and now I need to add a couple of changes to every course. Publishing them in a newest version of SL would make these instructions useless. 

Please advise.
