vim中de和dw有什么区别？

Question

以下vimtutor提示我在第2.3课中找到了以下内容:

Many commands that text are made from an operator and a motion.
The format for a  follows:

      d   motion

Where:
  d      - is the delete operator.
  motion - is what the operator will operate on (listed below).

A short list of motions:
  w - until the start of the next word, EXCLUDING its first character.
  e - to the end of the current word, INCLUDING the last character.
  $ - to the end of the line, INCLUDING the last character.

不过,我不明白之间的差别dw和de.使用dw和时的用例是什么de？

Answer 1

有这样的缓冲区:

Lorem ipsum dolor

将光标移动(?)在ipsum单词的中间:

Lorem ip?um dolor

现在按de:

Lorem ip?dolor

光标删除了当前单词中的字母,直到结束,但没有空格.

这样做时dw,空间将被删除:

Lorem ip?olor

Answer 2

dw 意思是"从这里切到下一个词".

before: fo[o]bar baz
        dw
after:  fo[b]az

de 意思是"从这里切到当前词的末尾".

before: fo[o]bar baz
        de
after:  fo[ ]baz
