if you messed up the buffer and want to start all over again.
43> Instead of using "/" to search, use "?" then paste.
You don't need to escape the frontslashes, so no need to edit the pattern.
If you wish to search forward, just hit "/" and Enter.
If you want to use it again, use the "?" history, not the "/".

Here Document 在vim里的妙用：
vim iWork/aaa.log < > :%s/.*/AAAAA/g

当然也可以把这个here document 放进for loop里面进行复杂的文本处理。
