This saves you from having to select an area the same size as the copy range when pasting: just point to the top left-most cell in the destination range and Ability will fill in the rest. In the following example, a new line for DM has been added:
You can copy the formulas in row 4 and make them work for row 5:
Select cells C4 through to F4.
Click the Copy button on the toolbar.

Click the Paste button on the toolbar to fill row 5 with formulas.
The above operations can also be used to move the contents of many cells to one cell, if Cut is used instead of Copy.
