Accessibility Options: Were there some, or did I dream it?

Hi Group

Tab order et al. have been noted quite a bit in the forums, but when I first played with Storyline many, many months ago, I seemed to remember finding an object-level properties panel that would let me set the name of the object and whether it was visible to screen readers and other accessibility agents - e.g. to 'make invisible' to screen readers a separator line or something that looked pretty but would just get in the way from an accessibility navigation point of view.

Hunt as I may, I can't find that properties panel in Storyline now.

Did I dream it, has it been taken away, or am I just not looking in the right place?

IF it does exist in the form that I remember, if an object is made invisible to a screen reader, would that also take it out of the tab order?

Thanks in advance to anyone who can confirm or deny this panel's existence.
