Undo and redo

Undo is per page; switching pages keeps each page’s own stack.

Toolbar Undo / Redo, or Ctrl+Z / Ctrl+Y. The left Execution list is draw order, not the undo stack — Main window layout.

Three things to remember

• Undo applies to the page you are editing. Switch pages and you undo that page’s actions.
• The stack is not saved when you close the project.
• Deleting an element also updates “refresh association” ticks that pointed at it; undo should restore the pre-delete state, including those ticks.

If an action will not undo, check whether you switched pages, and whether you are in the effect-demo window (demo does not write the design undo stack).
