For reporting the selection when selecting slides, I have written this issue up here: https://github.com/nvaccess/nvda/issues/12287

For reporting common actions like setting text bold and italic, there is already an issue for that: https://github.com/nvaccess/nvda/issues/5362 Note that as indicated in the issue, you can find out the formatting of any given text with NVDA+F, however it certainly would be useful to have it reported when setting it with say CONTROL+B.

In either case, please do add any extra information to the issue to add anything else.

Kind regards

Quentin.
