Office solution: Keyboard shortcuts for hiding and unhiding columns and rows

A couple of weeks ago, we asked for the keyboard shortcut that unhides columns and rows in Excel 2007. Reader Paul Blaser initiated this challenge after upgrading to Excel 2007. As you can see in Table A, the [Ctrl]+[Shift]+0 shortcut for unhiding columns doesn't work in Excel 2007 - at least, for some of us. Help files for Excel 2007 list the keystroke, so it should work, right?

Table A

Combo	Description	2003	2007	2010
[Ctrl]+0	Hides columns	Y	Y	Y
[Ctrl]+[Shift]+0	Unhides columns	Y	N	Y
[Ctrl]+9	Hides rows	Y	Y	Y
[Ctrl]+[Shift]+9	Unhides rows	Y	Y	Y

Another way to unhide a column follows:

1. Select the adjacent columns. Or, enter a cell reference to any cell in the hidden column into the Name box (to the left of the Formula bar).
2. Click the Home tab.
3. From the Format dropdown in the Cells group, choose Hide & Unhide.
4. Select Unhide Columns.

The keystroke equivalent to the above process is [Alt]+H+O+U+L. Unfortunately, this keystorke method isn't as efficient as [Ctrl]+[Shift]+0; why it doesn't work in Excel 2007 is still a mystery to me. If any of you figure it out, let us know!
