Outliner
To keep your scene orderly it's important to pay some attention to the naming of your objects and groups. To help you with this there is the Outliner. The Outliner can be opened with the button on the left side of your screen, and it will give you a list with all the objects in your Maya scene. If there are a lot of objects in your scene this can help you retrieve objects or groups more easily, or you can easily clean up objects that you don't need anymore.
