Thank goodness for the Undo feature. How many times have you been a little hasty in a dialog box and done something you really didn't want to do? Simply put, Undo reverses the last action taken on a document. For example, if you delete selected text, Undo brings it back. If you change the margins, Undo puts them back the way they were. The text will look as if you never took the action.
Undo has a twin feature called Redo. Redo reverses the last Undo action. If you accidentally undo too many things, Redo puts them back.
To use the Undo feature, perform one of the following actions:
Click the Undo button on the toolbar.
Choose Edit, Undo.
To use the Redo feature, perform one of the following actions:
Click the Redo icon on the toolbar.
Choose Edit, Redo.
The Undo and Redo buttons have drop-down arrows next to them. Click the arrow to display a list of the most recent actions (see Figure 3.3). Instead of repeatedly clicking the Undo or Redo buttons, you can choose an action from one of the lists. Stay with me now because this procedure gets a little tricky. If you choose an action from this list, all the actions up to and including that selected action will be reversed, not just the selected action.
Figure 3.3 Use the Undo and Redo history lists to select which action to undo or redo.
