You can use keyboard shortcuts in every office program. Here are four Excel Shortcut Keys that we find extremely useful:
Keys | Action | 
  
|---|---|
| CTRL + ; (semicolon) | Enters the current date into the selected cell | 
| CTRL + : (colon)  | 
    Copies the current time into the selected cell | 
| CTRL + ' (apostrophe)  | 
    Copies the data from the cell directly above into the selected cell | 
| ALT + + (plus sign)  | 
    Is the same as clicking on the AutoSum tool |
