Hi Curious, there is an Isolate function for that which is available with a right-click on the Edit > Hide button. It will keep the selected objects as the visible ones and hide everything else, retaining a memory of what everything else's state was. Then when you trigger it again it will restore back to the pre-Isolate state.

For a shortcut key it can be triggered by: moi.geometryDatabase.isolate();
