You can undo and redo actions in VRED, as you would in most applications, using Edit > Undo (Ctrl+Z) and Edit > Redo (Ctrl+Y). VRED also includes some features for managing Undo actions.

How to Clear an Undo Stack

This removes stored Undo actions to clear memory for other tasks.

In the Menu Bar, select Edit > Clear Memory Stack.

How to View the Undo/Redo History

This displays a brief history of actions in VRED.

In the Menu Bar, select View > Undo/Redo History.

How to View and Empty the Trash

The Trash container contains items deleted from your scene. These can be restored, using Undo. However, you can delete these items from the Trash to clear memory for other processes. Once an item is deleted, even using Undo cannot restored it to the scene.

To view and empty the trash:

• To view the contents of the trash, in the Menu Bar, select View > Trash.

• To empty the trash, in the Menu Bar, select View > Trash then right-click inside the Trash dialog box and select Clear.
