Discuss the use of the Undo, Redo, and Repeat commands.
What will be an ideal response?
Word remembers the editing and formatting changes you make so that you can easily reverse or repeat them. You can reverse the last action you took by clicking the Undo button on the Quick Access toolbar, or you can undo a series of actions by clicking the Undo list arrow and selecting the action you want to reverse. When you undo an action using the Undo list arrow, you also undo all the actions above it in the list-that is, all actions that were performed after the action you selected. Similarly, you can keep the change you just reversed by using the Redo button on the Quick Access toolbar. The Redo button appears only immediately after clicking the Undo button to undo a change. If you want to repeat an action you just completed, you can use the Repeat button on the Quick Access toolbar. For example, if you just typed "thank you," clicking the Repeat button inserts "thank you" at the location of the insertion point. If you just applied bold, clicking the Repeat button applies bold to the currently selected text. You also can repeat the last action you took by pressing [F4].
