vim中de和dw有什麼區別？

Question

繼vimtutor提示我發現在2.3課如下：

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. 

不過，我沒有看到W¯¯和dËd之間的差異。什麼是使用時的使用案例dw and de？

Answer 1

具有這樣的緩衝液：在ipsum字的中間

Lorem ipsum dolor 

移動光標（▒）：

Lorem ip▒um dolor 

現在按dÊ：

Lorem ip▒dolor 

光標刪除當前單詞中的字母，直到結束，但沒有空格。

在做d 瓦特，空間將被刪除：

Lorem ip▒olor 

Answer 2

dw意思是 「從這裏切下一個單詞」。

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

de表示「從這裏切換到當前單詞的結尾」。

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