Bottom-of-File line
A line marker, identifying the end of the file.
box block
A type of <block>. It is a rectangular portion of the
<filearea>.
column block

a columnar portion of every line in the file is included.
column target

command line

prompt, "====>", where THE commands are entered.
current column
The column in the <filearea>, marked by the "|" character on
the <scale line>.
current line
The line in the <filearea>, normally highlighted, from which
commands entered on the <command line> take effect.
cursor field
The "field" in which the cursor is currently located. This
can be the <prefix area>, <command line> or <filearea>.
filearea
That part of the screen display where the contents of the
file being edited are displayed.
focus column
The column in the <filearea> which currently has the focus. If
the cursor is in the <filearea>, it is the column on which the
cursor is displayed. If the cursor is in the <command line> or
<prefix area>, the focus column is the <current column>.
focus line

magic number
A magic number is used on Un*x systems to identify the type of
a file. It was originally used in binary files to identify the
file, but the concept was also extended to text files;
particularly shell scripts; to enable to shell to determine
which interpreter should be used to execute the contents of a
file. These magic numbers in text files are really magic "strings"

highlighting feature to automatically determine the <parser> to be
used to highlight a file.
