A range is identified by the cell references of the cells in the upper left and lower right comers of the range. These two references are separated by a colon (:) which tells Excel to include all the cells between these start and endpoints. An example of a range of adjacent cells would be B5: D10.

To select an adjacent range, click on a cell in a corner of your selection and drag the mouse over the remaining cells. For example, A1 through D6, D8 through E9, and B14 through D15 are written as A 1:D6 or D8: E9 or B14: D15.

• To select a non-adjacent range, first select an adjacent range of cells. Now, press and hold down the Ctrl key while you select another adjacent range of cells. Release the mouse button and the Ctrl key.
