Certain forms feature a Tabbed interface which allows for quick access to other forms, windows, and blocks related to the active form, window, or block. When a Tab is selected, the cursor is automatically forwarded to either the appropriate tabbed block or window within the current form, or to a tabbed block or window in another related form. Some tabs may be initially grayed-out. As you enter data into the form, tab titles will dynamically fill in making additional choices available.
