Undo and Redo

Designer HFC keeps a history of your design actions during the current work session. As such, you can click Undo to undo one action per click that you have taken up to the point you began working on a project. Once you save or close a project, you lose the ability to undo previous actions. Conversely, you can click Redo to repeat one action per click that you previously deleted with Undo in your session history.

Alternatively, you can use Ctrl+Z or Ctrl+Y to undo and redo, respectively.
