 * 1) Open View → Visibility
 * 2) Select Toggle all objects

In documents with many objects, or where it is difficult to locate an element in the structure, it may be useful to hide an object in the graphic view and then use View → Visibility → Toggle all objects to bulk switch the visibility and show in the graphics only the object that was previously hidden. This procedure used in conjunction with the other global selection commands, Show all objects and Hide all objects, often avoids tedious selection operations.

To hide or quickly display a series of functions, it can also be useful to group them and then activate or deactivate the groups.
