The Quick Access Toolbar menu provides a list of commands that the user frequently adds to the Quick Access Toolbar. Clicking More Commands... in the Customize Quick Access Toolbar menu opens the Customize Quick Access Toolbar dialog (see Figure 3), which allows the user to add or remove commands to/from the Quick Access Toolbar.

When there is not enough room for all the controls to fit in the Quick Access Toolbar, a chevron button appears on the right. Clicking this chevron button, the user can access the rest of controls via a pop-up window (see Figure 4).
