By its very nature as a spreadsheet, it's easy to create a series of numbers in Excel. For instance, you can enter the number 1 in cell A1, hold down the Ctrl key, and drag the fill handle in cell A1 down to create an instant series of numbers. For the uninitiated, the Fill Handle is the little black notch in the right-hand corner of the active worksheet cell. Regardless, most users don't realize that you can configure Excel to create a series of letters in a similar fashion.
First we need to create the list itself. If you like, you can type the letters A through Z down a column or across a row. But, there's an easier way:
1. In a blank worksheet, press F5 to display the Go To dialog box.
2. Enter A1:A26 in the Reference field, and then click OK.
