You could unprotect the worksheet.
Visit JE McGimpsey's site:

Or you could toggle a setting.
Tools|Options|transition tab|check transition navigation keys.
Then find an unlocked cell and type = (just an equal sign)
Then use the mouse (or arrow keys) to drag through the hidden column range.
That unlocked cell could be on any worksheet if you don't have unlocked cells
available.
