                                    Further, you can define custom data series whose items don’t change by a certain
                                    increment (such as a series of company locations like Chicago, Pittsburgh, Dallas, and
                                    Boston) and then generate the custom series in a spreadsheet by simply entering its
                                    first item in a cell and then dragging the Fill handle as you would with any incremented
                                    series. To create the custom list, you open the Custom Lists tab of the Options dialog
                                    box (Tools➪Options). There, you type the individual items in the series (terminated by
                                    the Enter key) in the List Entries list box in the order in which they are to be generated
                                    with the Fill handle and then select the Add button. Alternatively, if this custom series
                                    already exists in a cell range somewhere in the spreadsheet, select the cell range in the
                                    worksheet after selecting the Import from Cells text box and then select Import.



                          Use Range Names


                                    The use of range names in a spreadsheet provides several important benefits, perhaps
                                    the most important of which is that you can use the range name to both move and
                                    simultaneously select the cell range in a flash, no matter where this range is located in
                                    the entire workbook. After a range is named, all you have to do to select the range is to
                                    choose its range name from the Name box drop-down list on the Formula toolbar.

                                    This method of selecting cell ranges can be a tremendous time-saver when you’re deal-
                                    ing with a table or list of data that you find yourself referring to or editing on a regular
                                    basis. This is all the more true if the named range’s data tables or lists are located in
                                    columns and rows in some distant region of a worksheet.

                                    Remember that you can use range names to select cell ranges with data tables or lists
                                    that you print on a regular basis. All you have to do is select the cell range with the
                                    Name box, and then open the Print dialog box (Ctrl+P) and select the Selection option
                                    button in the Print What section before you select the OK button.

                                    The second important use for range names is to define and name a constant (such as
                                    a tax rate or interest percentage) whose value you need to refer to in the formulas
                                    you’re about to build in a data table or list but which you don’t want to enter in the
                                    worksheet as a separate cell entry. To do this, open the Define Name dialog box
                                    (Insert➪Name➪Define), and enter the name for the constant in the Names in Workbook
                                    text box. Next, set the name equal to the value or the formula that calculates the value
                                    you want used in the Refers To text box before you select OK. Then, to refer to the
                                    constant in a formula you’re building, select its name in the Paste Name dialog box
                                    (Insert➪Name➪Paste) before you select OK.

                                    The final important use for range names is in documenting the functioning of the for-
                                    mulas in your data tables in a spreadsheet. You can do this by having Excel apply the
                                    table’s row and column headings to the cells of the table. Simply select the table
                                    including the cells with the row and column headings before you open the Create
                                    Names dialog box (Insert➪Name➪Create) and then select the appropriate check boxes
                                    (Top Row, Left Column, Bottom Row, or Right Column) that contain the row and
                                    column headings before you select OK. Then, to replace the cell addresses in the
                                    formulas in this table with the new range names, open the Apply Names dialog box
                                    (Insert➪Name➪Apply) and with the Use the Row and Column Names check box
                                    selected, select the OK button.
