Excel shortcut for copying formulas

I found another quick Excel shortcut the other day.  (Courtesy of LifeHacker) When you want to copy a formula down a column, I typically grab the bottom right corner of a cell, and drag the mouse down through all the cells I want to copy the formula too.  This is pretty easy and fast, which is probably why I never found this new shortcut before.  An even quicker way is to simply double click on the bottom right corner of a cell, and it will automagically fill all the cells downward in the column until the last one with data in the column to the left.  Example:

Here I have a column on the left with data, and the column on the right with a simple formula that I want to apply to that data.  Typically I would just grab the bottom right corner and drag down to copy the cell.


An even faster way is to double click when the cursor changes to the black cross, and it will automagically copy the formula for you.
