Show All Hidden Objects
If you have hidden objects from the 3D view, and the selection toolbar is no longer visible, you can quickly show all objects again by clicking the Show All Hidden Objects in the main toolbar.
Ghost mode is great when you are trying to give context to the visible objects.
To use ghost mode
Select some objects and use either Hide Selection or Show Only to have some objects visible and others hidden.
3. Turn on Ghost Mode (located in the main toolbar).
4. The hidden objects will be shown with a high transparency but cannot be selected.
