The Main Toolbar is a collection of buttons that provide access to common actions within OneTouch®. The main toolbar is displayed along the top edge of the OneTouch® Application Desktop (although you can reposition it along the bottom, left, or right edge from the Options | Preferences Advanced dialog).
Not every button on the main toolbar will be "active" all of the time. A button will be grayed out when it is inactive. For example, the button (Copy) will be grayed out if there is no current selection to copy to the Clipboard.
