Show me how to use zoom in Microsoft Excel 2007

Excel -> Microsoft Excel 2007

Problem: I want to shrink or enlarge the spreadsheet.

Open Microsoft Excel 2007
Click the "Zoom In" button at the bottom right of the screen (it looks like a "+" symbol on a round button)
Click the "Zoom Out" button (it looks like a "-" symbol on a round button)
Click-and-drag the slider to the right or the left to increase or decrease the zoom factor
Click the "Zoom Level" button (in other words, click on the zoom percentage display - e.g., 100%, 140%, 71%, etc.)
Click the "Cancel" button
Click the "View" tab
On the "Zoom" section, click the "Zoom" button
Click the "100%" button
