Isolate selection in another program – 3DS Max. How it works?

There is a keyboard shortcut: Alt+Q = Isolate selection

In 3DS Max 2012 and previous versions while the Isolate Tool is active, a dialog labeled ISOLATED SELECTION appears.

Exit Isolation — Click to end isolation, close the dialog, and unhide the rest of the scene. The views are restored to what they showed before you chose Isolate Selection.

In 3DS Max 2013  the “isolate selection” was changed. Alt+Q toggles the isolation. Dialog window doesn’t appear and it’s impossible to use isolate selection one after another to get deeper in complex models with many objects how it was possible before.  There is also icon on the bottom of the viewports which do the same as a keyboard shortcut.

In 3DS Max 2014 as I heard the possibility to use isolate selection one after another was restored.

Note: Isolate Selection works only at the object level. You can’t choose it while at the sub-object level. If you go to a sub-object level while working with an isolated object, you can click Exit Isolation, but you can’t isolate sub-objects.
