Another way to navigate through the database model is using the magnifier tool. This one basically shows a portion of the zoomed-out model where the mouse cursor is placed but using the normal scaling so the user can identify which object is currently focused. In order to see this feature in action, in a zoomed-out model (zoom factor less than 100%) hold
Ctrl + Alt so that a preview box (see the right portion of the image below) appears on one of the bottom corners of the canvas. Once displayed the magnifier tool, it's possible to move the mouse over the canvas and see the section covered by it (blue rectangle) being shown in the preview. In this mode, it is possible to select the focused object using a left-click or even activate the context menu through right-clicking.
