Microsoft Office shortcuts

1. Ctrl+Z is the magic undo combo. It simply undoes your last action, say, the paragraph you accidentally erased (it works in other applications, too--try it on the Photoshop filter you really wish you hadn't applied, or after renaming a document or a folder in a Windows directory). Programs vary in the number of times you can undo something, but some will let you Ctrl+Z all the way back to the beginning. (And, yes, there is a redo command, just hit Ctrl+Y.)
   
2. Ctrl+B, Ctrl+I, or Ctrl+U apply bold, italics, or underline to highlighted text, respectively.
   
3. Ctrl+P prints whatever is in an active window.
   
4. Ctrl+Backspace erases an entire word at a time, instead of a letter. Ctrl+up or down arrows let you scroll an entire paragraph at a time, instead of one line, and Ctrl+Shift+up or down arrow will select an entire paragraph.
   
5. Ctrl+Enter inserts a page break in Word.
   
6. Alt+Ctrl+C inserts the copyright symbol (Alt+Ctrl+R inserts the registered trademark symbol, and Alt+Ctrl+T makes the trademark symbol).
   
7. In Outlook, you can jump to the section you want: Ctrl+1 switches to the Mail window, Ctrl+2 switches to the Calender, Ctrl+3 to Contacts, Ctrl+4 to Tasks, and Ctrl+5 to Notes.
   
8. Ctrl+Shift+M starts a new message in Outlook. (Use Ctrl+Shift+C for a new contact.)
   
9. In Outlook e-mail, hit Ctrl+N to compose a new message, Ctrl+R to reply to a message.
   
10. The only Excel shortcut I've ever known, Ctrl+, enters the date.
