Discovered this in Writer but also tested and found the same behavior in Calc. When you switch the UI via View | User Interface to Tabbed, Tabbed Compact, Groupedbar Compact, or Contextual Style, the Alt+<hotkey> combinations not longer work to activate the menu items, nor does F10 or arrow/cursor keys. If you reveal the classic Menu, the Alt+<hotkeys>, F10, and arrow/cursor keys work, but only on the classic Menu. I can shoot a video of this if that's helpful.
