The status bar

Besides the messages that appear in the center of the status bar from time to time,the status bar has a number of fields which record various settings of options of the editor. On the left side is the line number. On the extreme right is the buffer name. Then just to the left of the buffer name are nine character fields which indicate settings of the editor.
