I love how much PowerPoint on Mac became accessible in a short period of time!
I'm on fast track 15.39 (170919), and I have some suggestions to make it easier for Voiceover user to use PowerPoint during presentation mode.
1. Presenter view:
Voiceover doesn't seem to be able to read the content of slides during presenter view. It just says image.
2. Highlight:
Visually Impaired users cannot use pointer, so it would be great if the texts are editable during the presentation, so we can bold, highlight, and so on during the presentation to emphasize. WE can do it while editing the slide, but it would be great if we could do it while presenting too.
3. Copy text:
If a slide has a long text like quote, we just have to memorize them, hoping that we don't screw up, or we have to ask for volunteer from audience to read it. It would be great if we can select some text part of a slide and copy. Then we can have speech synthesizer to speak what's on the clipboard.

Thank you for improving Microsoft Office better on Mac everyday!
