Any object that can be picked up and dragged is pliant, and every cell in a spreadsheet and every character in a word processor document is pliant. 任何可以捡起来或者拖动的对象都是受范的，每个表格上的小格或者字处理软件处理的文档中的一个字都是受范的。
Many undoable actions are data-free transformations such as a paragraph reformatting operation in a word processor or a rotation in a drawing program. 很多能够可撤销的操作没有数据变化，就像在字处理软件中重新设置段落格式或者画图程序中的旋转那样。
