Using tabs in the work area, you can visualize multiple graphs and edit them simultaneously, minimizing the need to re-graph. You can create new tabs, rename or duplicate them, delete and restore them, and re-order them in the Node Editor.
Tab information is retained when you close the Hypershade, and saved with the scene.
To create a new tab, click + beside the right-most tab.
To delete a tab, right-click the tab and select Close Tab; or, middle-click the tab to delete it..
To restore the last tab that you deleted or closed, click in the work area toolbar. This icon becomes active when you have deleted a tab.
To rename a tab, double-click its name. Press Enter or click outside of the tab to commit your change. Press to cancel.
You can also right-click the tab and select Rename Tab.
To duplicate a tab, right-click the tab and select Duplicate Tab.
Left or middle mouse drag to re-order tabs.
