Here you go – sorry I couldn’t get one when I initially posted – my curriculum went live today, so I was in a flurry of final QA, cleanup and SCORM-ing on Friday.
The issue shows up in the Adult Maltreatment Intakes chapter. At the chapter level, there is a group of buttons that appear on all pages in the chapter (Tree View nodes). The goal is that for the Adult Maltreatment Report section, those buttons come after the buttons at the top of the screens (AMR tabs) FWIW, there is a reason I need the AMR tabs group on each page.
If I set the Tree View nodes to last in reading order, they do come in last, after both the audio and navigation buttons. But, the main issue is that the tab order goes from the bottom up when I have reading order last. On a side note, this also happens in the “Navigation buttons” group at the title level.
Everything I interpreted from the Help info is that tab order would always be top down, but it seems that reading order to last changes this so that elements in groups are bottom-top instead.
