strikethree

In the "Help" button of Excel, do a search for "shortcut" and you will find tutorial on a number of shortcuts. Supersadface is right, try to limit the use of the mouse. With Excel 2007, I find ribbons to be very helpful in cutting time. The problem with ribbon is that when you use someone else's Excel and if he/she doesn't have ribbon, you'll spend a lot of time finding commands through the menu bar.
