The programs in the Office 2010 suite — Word 2010, Excel 2010, PowerPoint 2010, Outlook 2010, Access 2010, and Publisher 2010 — have these indispensable commands in common:
Undo: Don’t despair if you give a command and then realize that you shouldn’t have done that. You can undo your mistake by clicking the Undo button (or pressing Ctrl+Z). The Undo command reverses your last action, whatever it happened to be. Keep clicking Undo to reverse several actions. You can also open the Undo drop-down list and undo many commands.
Repeat: Click the Repeat button (or press F4 or Ctrl+Y) to repeat your latest action, whatever it was, and spare yourself from having to do it a second time. You can move to another place in your file before giving the command.
Recent: On the File tab, choose Recent to see a list of the previous 22 files you opened. Click a file on the list to open it.
Zoom: Use the Zoom controls in the lower-right corner of the screen to prevent eyestrain and make your work more efficient. Drag the Zoom slider to shrink or enlarge what’s on-screen. Click the Zoom In or Zoom Out button to zoom in or out by 10-percent increments. If your mouse has a wheel, hold down the Ctrl key and spin the mouse wheel to zoom.
