The Toolbars offer quick access to the features used most frequently in AFT xStream. The figures below show the Toolbars. There are actually six toolbars in all. One is the Common Toolbar, and it is always shown. Its features are common to all five Primary windows. In addition, there is one Toolbar for each Primary window, offering features appropriate for work in that window. You only see two Toolbars at a time in AFT xStream. The function of each icon in a given Toolbar appears when you pass the mouse over the icon button without clicking on the button. Each of the functions on the Toolbar is also available through the menu system.
