Most icons marked with the small arrow can become floating toolbars.
Floating toolbars can be re-docked on an edge of the screen or within one of the existing toolbar areas at the top of the screen, as described in Chapter 4. To do so, click the area at the top of the sub-menu, drag it across the screen, and then release the mouse button.
You can make a sub-menu into a floating toolbar. You may wish to keep this sub-menu displayed on your screen, but in a different position. Click the arrow, and a sub-menu or floating toolbar appears, showing its additional functions (see Figure 6). The arrow indicates that this icon has additional functions. Many toolbar icons are marked with a small arrow.
