Since they're still publishing a text-based newsletter, it's almost impossible to point you in the direction of the original content at this moment. That said, from the latest issue of Office for Mere Mortals (the beginner's Microsoft Office newsletter part of Woody's Watch) comes a series of cool “secret” keyboard shortcuts for Excel, the ever-popular spreadsheet application:

Shift + Open becomes Save As
Shift + Save becomes Open
Shift + Print becomes Print Preview
Shift + Print Preview becomes Print
Shift + Sort Ascending becomes Sort Descending
Shift + Sort Descending becomes Sort Ascending
Shift + Underline becomes Double Underline
Shift + Double Underline becomes Underline

I don't use spreadsheets that often, and I've definitely seen spreadsheets used improperly many times. Ever have someone send you an Excel spreadsheet filled with content better suited for a Word document or PowerPoint presentation? Yeah, me too.
