JE McGimpsey mentioned this keyboard shortcut in a post back in June 2008.

It appears to change all cells in a spreadsheet from dates to date serial
numbers and vice versa. But I can't find any mention of the shortcut in
Excel 2003 Help. Can someone tell me where it is in Help or explain what it
is supposed to do? For example, is it supposed to operate on the whole
spreadsheet? Can it be applied to selected cells only?
