/BEGINNING (D)

    Indicates that the cursor should be left at the beginning of
    the second line. If you position the cursor at the end of the
    original line, the /BEGINNING qualifier adds a new blank line to
    the current buffer and repositions the cursor at the beginning of
    the new line.

    If you position the cursor at the beginning of a line, the
    /BEGINNING qualifier adds a new blank line before the current
    line and the cursor remains at the beginning of the current line.

    If you position the cursor within a line, the /BEGINNING qualifier
    splits that line into two lines at the original cursor position
    and repositions the cursor at the beginning of the second line.
