The title bar is the top part of a plot document, worksheet document, grid document, dialog, etc. that contains the name of the window or dialog. Drag the window or dialog by the title bar to reposition it. Double-click on the title bar to maximize or restore a window.
When a document contains unsaved changes, an asterisk (*) appears next to its name in the title bar. The asterisk disappears once the unsaved changes have been saved.
