Reply To: article panel does not work

I have now been trying to teach myself from the Adobe videos to use the Articles panel. First of all, the link below posted by David in answer to the first query now does not work so could I have the correct link please:

I am confused about the images. The video tells us about clicking on each item and dragging to the panel to correct the reading order. But clicking on the image does not work. It is anchored though, and has alternative text. If the text around the image is dragged into an article and it includes the positioned anchor, will the alternative text in the anchored image be read at the appropriate moment?

And is there a way to easily test this; that is, is there an easy way to activate what would happen if the file was exported to pdf and then I used a reader to test it?

I’d really rather just use this panel than the structure panel as well. Is that possible?
