Marked selection is already blue, so that should be something different.

No, because Alt+Space opens the window menu in at least GNOME and other window
managers.

Anything ScOutputData would be wrong because it's not related to data at all,
nor styles. It also wouldn't be a background.

Take a look at ScTabView::MarkRows() and ScTabView::MarkColumns(), which are
called for .uno:SelectRow and .uno:SelectColumn, it would be almost the same
(without the actual mark and selection of course) and should be a
HighlightOverlay added to the OverlayManager, similar to the SelectionOverlay
that is updated from InitBlockMode() as ScGridWindow::UpdateSelectionOverlay(),
e.g. like UpdateHighlightOverlay() and so on. They could share a great portion
of code.
