|   Whatever you do to your worksheet, you can undo, as long as you don't close the worksheet or exit Excel. To undo your most recent action, simply click the Undo button or press Ctrl+Z . You can click Undo or press Ctrl+Z several times to back through a series of changes. You can even undo the Undo command by clicking the Redo button or pressing Ctrl+Y . Next to the Undo button is a downward-pointing arrow that opens the Undo menu. This menu contains a list of all the actions you performed, starting with the most recent. Contrary to what you might think, the Redo menu does not enable you to pick any action in the list to undo. When you pick an action down the list, that action and all actions that were performed after it are undone. In other words, you can undo the most recent action or the five most recent actions, but you cannot undo only the seventh action. To undo several actions, open this menu and click the last action you want to undo. Excel undoes the selected action and all actions performed after that. (Redo has its own menu, as well.) The Absolute Minimum The single most important and most time-consuming chore you face when you create a worksheet or workbook is data entry , and now that you have completed this chapter, you know everything you need to know, and then some, about entering various types of data in cells . You now know how to Move from one cell to another and use the scrollbars to bring additional cells into view. Enter labels, values, dates, and times, and adjust the number formats so that the numbers actually look like dollar amounts, percentages, dates, and times. Double-check your data entries as you type them by having Excel read them aloud to you. Copy a cell entry into numerous cells and even fill several cells with a series of entries by using Auto Fill. Replace or edit data entries. Select, move, copy, and delete cell entries. Undo your most recent edit or command, and undo the Undo command. With the skills you acquired in this chapter, you can create a basic worksheet consisting of labels and values. You can even dress it up a little by formatting numbers as dollar amounts and percentages. You may have found, while working through this chapter, that you have a tough time making all your data entries fit into those tiny boxes. Fortunately, the next chapter shows you how to take control of rows, columns , and cells to give your data more room to spread out. |  |
