Using Undo and Redo

Most operations are reversible. The Undo and Redo commands work with changes that affect the visual diagram, layout of elements, addition of Attributes and Operations, and so on.

• To undo the last change made to the diagram, select Edit > Undo from the menubar, or press CTRL+Z.
• To restore the last change made using the undo command, choose Edit > Redo from the menubar, or press CTRL+Y.
