Smart Automatic Focus of Lower Zone when Mouse Over

Hey, when working with Spectralayers in the lower zone, I’d like to be able to mouse over between Cubase project/arranger/edit window and SL and just have my key commands work depending on where the mouse is without having to mouse-click myself into each zone.

The keyboard focus system in Windows and macOS is usually tied to the focused window, which is the last-clicked window. Anyway, that would be a Cubase request, not a SpectraLayers request.
