Undo and Redo in Microsoft Forms
Microsoft Forms supports multiple levels of Undo and Redo commands. This means you can undo a series of actions, not just a single action.
CTRL+Z is the shortcut key for Undo; CTRL+Y is the shortcut key for Redo.
You cannot undo or redo layering commands, such as Send To Back or Bring To Front. For example, if you select an object and click Move Backward on the shortcut menu, you will not be able to undo or redo that action.
