This has been reported for earlier betas, but I thought I would flag it again (it has now been buried beneath so many more recent posts that I couldn’t find it, so I imagine the devs might have lost track too).
Many of the standard keyboard shortcuts (e.g. Ctrl-Shift-V for unformatted paste, or Ctrl-i for italic) don’t work in the inspector panel. These would be really useful when formatting footnotes, for example.
