# Undoing and redoing

Almost all actions in the diagram tool are undoable. Every action that can be undone, can also be redone. For advanced undoing, open the history tool.

Tip: Undo actions cannot be undone. Use redo to undo an undo action.

- To undo the last action, click Undo last action.
- To redo the last action, click Redo last action.
- To undo all actions up until a specific action:
  1. Click the History tool button.
  2. The History tool dialog appears with a list of all undoable actions. By clicking on one of the actions, the diagram returns to the state it was in just after you performed this action.

Note: When an action is performed that cannot be undone, the history tool is emptied.
