-Enter two-column mode with the current buffer on the left, and on the
-right, a buffer whose name is based on the current buffer's name
-(@code{2C-two-columns}). If the right-hand buffer doesn't already
-exist, it starts out empty; the current buffer's contents are not
-changed.
-
-This command is appropriate when the current buffer is empty or contains
-just one column and you want to add another column.
-
-@item @kbd{@key{F2} s} or @kbd{C-x 6 s}
-@kindex F2 s
-@kindex C-x 6 s
-@findex 2C-split
-Split the current buffer, which contains two-column text, into two
-buffers, and display them side by side (@code{2C-split}). The current
-buffer becomes the left-hand buffer, but the text in the right-hand
-column is moved into the right-hand buffer. The current column
-specifies the split point. Splitting starts with the current line and
-continues to the end of the buffer.
-
-This command is appropriate when you have a buffer that already contains
-two-column text, and you wish to separate the columns temporarily.
-
-@item @kbd{@key{F2} b @var{buffer} @key{RET}}
-@itemx @kbd{C-x 6 b @var{buffer} @key{RET}}
-@kindex F2 b
-@kindex C-x 6 b
-@findex 2C-associate-buffer
-Enter two-column mode using the current buffer as the left-hand buffer,
-and using buffer @var{buffer} as the right-hand buffer
-(@code{2C-associate-buffer}).
-@end table
- @kbd{@key{F2} s} or @kbd{C-x 6 s} looks for a column separator, which
-is a string that appears on each line between the two columns. You can
-specify the width of the separator with a numeric argument to
-@kbd{@key{F2} s}; that many characters, before point, constitute the
-separator string. By default, the width is 1, so the column separator
-is the character before point.
-
- When a line has the separator at the proper place, @kbd{@key{F2} s}
-puts the text after the separator into the right-hand buffer, and
-deletes the separator. Lines that don't have the column separator at
-the proper place remain unsplit; they stay in the left-hand buffer, and
-the right-hand buffer gets an empty line to correspond. (This is the
-way to write a line that ``spans both columns while in two-column
-mode'': write it in the left-hand buffer, and put an empty line in the
-right-hand buffer.)
-
-@kindex F2 RET
-@kindex C-x 6 RET
-@findex 2C-newline
- The command @kbd{C-x 6 @key{RET}} or @kbd{@key{F2} @key{RET}}
-(@code{2C-newline}) inserts a newline in each of the two buffers at
-corresponding positions. This is the easiest way to add a new line to
-the two-column text while editing it in split buffers.
-
-@kindex F2 1
-@kindex C-x 6 1
-@findex 2C-merge
- When you have edited both buffers as you wish, merge them with
-@kbd{@key{F2} 1} or @kbd{C-x 6 1} (@code{2C-merge}). This copies the
-text from the right-hand buffer as a second column in the other buffer.
-To go back to two-column editing, use @kbd{@key{F2} s}.
-
-@kindex F2 d
-@kindex C-x 6 d
-@findex 2C-dissociate
- Use @kbd{@key{F2} d} or @kbd{C-x 6 d} to dissociate the two buffers,
-leaving each as it stands (@code{2C-dissociate}). If the other buffer,
-the one not current when you type @kbd{@key{F2} d}, is empty,
