Copying Microsoft Excel Cells to Fill a Range
Excel provides a pair of nifty shortcut keys that can be used to copy cells down and to the right. For instance, let’s say you want to copy the contents of cell C3 to the fifteen cells just below it. All you need to do is select the sixteen cells (making sure that cell C3 is the top cell in the selection) and then press Ctrl+D. Cell C3 is copied to all the other cells below it.
