还有来自的解释:

先说Cheat Sheet，这里面有个Cheat（欺骗），想当然的话，意思肯定不好。事实上，这Cheat Sheet 的原意的确也就是“小抄”的意思。所以，字典的定义是：“A piece of paper with information written down on it that an unethical person might create if they weren't prepared for a test.”（由于对考试准备不足，夹带写着考试内容的纸条，此为品行不高的人所为。）然而，曾几何时，Cheat Sheet这个说法走出了贬义的阴影，成为“简单说明、步骤说明书”。如：We asked the IBM Engineer to develop a cheat sheet for this machine. 我们要求 IBM 公司的工程师给我们搞个简单的机器操作说明书。The cheat sheet was attached to the package of the fancy camera. 说明书就贴在高级照相机的包装盒上。
