Reverses any editing change to a document, returning everything to its previous state before the last change. Use “Undo” when you change your mind about a command or a change. “Undo” is dimmed when it is not available. “Undo” is also undoable itself. If you are not sure that you want to “Undo” something, you can try it and, if the effect is not right, just “Redo” again.
