To protect you from mistakes, Office 2007 offers a special Undo command, which essentially tells the computer, "Remember that last command I just gave? Pretend I never chose it."
You can use the Undo command any time you edit data and want to reverse your changes. The two ways to choose the Undo command are
Click the Undo icon on the Quick Access toolbar (see Figure 2-6). Press Ctrl+Z.
The Undo and Redo icons appear on the Quick Access toolbar.
Sometimes you may make many changes to your file and suddenly realize that the last five or ten changes you made messed up your data by mistake. To undo multiple commands, follow these steps:
1. Click the downward-pointing arrow that appears to the right of the Undo icon.
A list of your previously chosen commands appears.
2. Move the mouse pointer to highlight all the commands that you want to undo, as shown in Figure 2-7.
3. Click the left mouse button.
Office 2007 undoes your chosen commands.
Downward-pointing arrow to the right of the Undo icon lets you view a list of your last commands.
Until you choose the Undo command at least once, the Redo icon appears dimmed. The Redo command lets you reapply the last command you chose to undo. The two ways to choose the Redo command are
Click the Redo icon (refer to Figure 2-6). Press Ctrl+Y.
Each time you choose the Redo command, you reverse the effect of the last Undo command. For example, if you use the Undo command four times, you can choose the Redo command only up to four times.
Sharing Data with Other Office 2007 Programs
Cutting, copying, and pasting data may be handy within the same file, but Office 2007 also gives you the ability to cut, copy, and paste data between different programs, such as copying a chart from Excel and pasting it into a PowerPoint presentation.
