Project Window
The Project window provides an overview of the project, and allows you to navigate and perform large scale editing.
Edit History Dialog
The Edit History dialog contains a list of all your edits. This allows you to undo any actions in the Project window as well as in the editors.
Branches
You can gather actions in branches. This way you can undo whole branches instead of every single action that you performed.
Undoing Edits of Separate Branches
If you have two or more branches, you can choose to undo edits of the separate branches.

Undoing Edits of Separate Branches

If you have two or more branches, you can choose to undo edits of the separate branches.

Procedure

Select Edit > History.
In the lower part of the Edit History dialog, click on a branch to select it.
The corresponding actions are listed in the upper part of the dialog.
Click Activate Selected or click a second time on the branch to activate it.

All actions from the subsequent branches are undone while all actions of the now active branch are redone.

If you undo some of the actions and then perform new edit operations, a new child branch is created at that position in the tree.
