As with all Windows applications, the toolbars provide quick access to the more frequently used menu commands. That is to say, the commands available from toolbars are a subset of the menu commands. In Excel2000 the Standard and the Formatting toolbars are docked together on one row by default. This means that only part of each toolbar is visible. To see the hidden part, click on the double arrow. If you prefer to have the toolbars on separate rows, open the Customize dialog box as explained above and clear the check mark from the box labelled Standard and Formatting toolbars share one row.
The amount of space allocated to each toolbar when they share a row may be changed. With the mouse, click on the vertical bar to the right of the first double arrow and drag it to one side.
