Riding piggy-back on last week's keyboard shortcuts are these - five more of my favorites. Try them!

 
Windows-M:  Minimizes your window

Ctl-Y:  I think of this one as Yet again. Whatever you type before pressing this combo will repeat the typing. So, for example, if you want a sheet filled with the phrase, "Pay the Ransom Now!" you type it, then press Ctl-Y. I know what you're thinking... when will you ever use this shortcut since you don't plan on kidnapping anyone soon. Well, it seems that once you know about this tip, opportunities abound.

 

Ctl-2  double-spaces selected text (conversely, Ctl-1 reverts it back to single spacing)

 

F7 opens spell check 

 

F9 in Outlook: Send/Receive mail (no need to wait for the auto-delivery every so many minutes)
