On macOS the menu bar's Select All, Cut, Copy and Paste (keys or clicks) act on a focused field too, and elsewhere the in-window menus' do: the field that had the keyboard when the menu opened gets them, with its selection, and the keyboard back (#516). Not yet: Select All across threaded frames (one frame's text is selected).
   - With the Artboard tool, Cmd/Ctrl+A after a click on a row of the Artboards panel selects every artboard, as the macOS menu bar's Select All does then; the active artboard stays active, and the art's selection does not change. After a press outside the panel's list, Cmd/Ctrl+A selects every object again. It used to select every object after a click in the panel too.
