Office challenge: What's the shortcut for unhiding columns and rows in Excel 2007?

This week, Excel 2007 has dropped a favorite keyboard shortcut; can you help a TechRepublic member find a new one?

Reader Paul Blaser misses the keyboard shortcut, [Ctrl]+[Shift]+0, for unhiding hidden columns and rows in Excel 2007. The [Ctrl]+0 shortcut still hides rows and columns, but its counterpart for unhiding doesn't. Can you help Paul?
