The titlebar is the line displayed at the top of the editor. There are
three sections: left, center and right. The section on the left displays
the version of nano being used. The center section displays the
current file name, or "New Buffer" if the file has not yet been named.
The section on the right will display "Modified" if the file has been
modified since it ws last saved or opened.
Special modes: When nano is in "File browser" mode, the center section will display the current directory instead of the filename. See section The File Browser.
Go to the first, previous, next, last section, table of contents.
