对于作者使用的写作表现形式（如列表，文字前面作为强调的圆形符号，栏框等所有在空白处额外体现的东西），要加以充分利用。
Use all the tools the author provides -- lists, bullets, sidebars, anything extra in the margins.
通常要复制卡片，并且将特殊的符号写到栏73到60上，以标明另一个版本。
Usually the CARDS were duplicated and special notations written on columns 73 to 60 to denote another version.
您还应该注意到，对应于左边一栏的每一个符号，右边一栏中都有一个相同颜色的小框。
You should also note that corresponding to each symbol in the left column, there is a small box in the same color in the right column.
