When you edit a Word2010 document, if you do not do the right thing and want to return to the state before the current result, you can do so by using the undo type or redo Type feature. The undo feature retains the most recently executed record of operations, and the user can undo several steps in order from the back to the top, but not selectively undo the discontinuous operation. The user can press the Alt+backspace key combination to perform the undo operation, or click the Undo typing button in the Quick Access Toolbar, as shown in Figure 1.
Figure 1 After you click the Undo Type button to perform the undo operation, you can also restore the Word2010 document to the most recent edited state. When a user performs a undo operation, the user can press the Ctrl+y key combination to perform a restore operation, or click the Recover Type button that has become available in the Quick Access Toolbar, as shown in Figure 2.
