Did you know: it's very easy to link the 3D editor selection box to the scroll reference line
Just press ctrl + left mouse click on the navigation after having made the 3D selection box. The selection box is then linked to the navigation, turning the navigation into the scroll reference line. You can now use the key combinations ctrl + → and ctrl + ↓ on your keyboard to move the scroll box up and down along the scroll reference line.
