Move to the cell you want to add content to and start entering the content as you would in Home view. Press Ewhen you have finished. You can also enter content into a number of cells with a single entry. Just select the cells, enter the content—for example, =Row*3—and press E.

What you enter on the entry line is evaluated as soon as you press E, with the result placed in the cell or cells. However, if you want to retain the underlying formula, precede it with S.. For example, suppose that want to add cell A1 (which contains 7) to cell B2 (which contains 12). Entering A1+B2Ein, say, A4 yields19, as does entering S.A1+B2 in A5. However, if the value in A1 (or B2) changes, the value in A5 changes but not the value in A4. This is because the expression (or formula) was retained in A5. To see if a cell contains just the value shown in it or also an
