The Toolbar

You can find the Toolbar at the top of the Unity Editor. It is not a window, and is the only part of the Unity interface that you can’t rearrange.

The Toolbar consists of several groups of controls. Each relate to different parts of the Editor.

Built-in scene tools such as the move tool are Gizmos, and you can create custom Gizmos using textures or scripting. Some Gizmos are only drawn when the GameObject is selected, while other Gizmos are drawn by the Editor regardless of which GameObjects are selected.
