Hi albehany, you can use the Isolate function of the Edit > Hide button to do that, it's available by right-clicking on the Edit > Hide button.

The first time you use it, it will keep the selected objects visible and hide all others but retain a memory of how things were. Then when you want to return right click on it again and it will restore everything to its pre-isolated state.

If you want to set up a keyboard shortcut for it, put in the following for the "Command" part of the shortcut key:

script: moi.geometryDatabase.isolate();
