Toolbar icons with a small black triangle will display submenus, tear-off toolbars, and other ways of selecting things, depending on the icon.
The tear-off toolbars can be floating or docked along an edge of the screen or in one of the existing toolbar areas. To move a floating tear-off toolbar, drag it by the title bar. See
