You can use the commands and other elements of the Quick Access Toolbar tab to customize the Quick Access Toolbar. This works in much the same fashion as the Customize Ribbon tab, with a few minor differences. As there is much less of an organizational structure to the Quick Access Toolbar, your options here are mainly limited simply to adding or removing commands and rearranging the order of commands. But you can also add sections to the Quick Access Toolbar for the purpose of organizing commands by using visual borders called separators.
