d 删除
w 单词
将两个字母组合起来就是 删除单词

{number}{command}{text-object}

d Delete
c Change  delete and enter insert mode
y yank
>  intend 缩进
v 选择

w 移动到下一个 word 开始
e 移动到下一个 word 的结尾
b 移动到上一个 word 的开始 back
2j   向下移动 2 lines

w => words 表示移动一个单词
s => sentences 移动一个句子
p => paragraphs 向下移动一个段落
t => tags  (html xml)

a => all
i => in
t => 'till
f => find forward
F => find backward

iw => inner word
it => inner tag
i" => inner quotes
ip => inner paragraph
as => a sentence

d => delete(also cut)
c => change(delete, then into insert mode)
y => yank (copy)
v => visual select

diw  delete in word，即使光标在 word 中也能够快速删除 word
yi)  yank all text inside the parentheses，光标在 `()` 中复制括号中的所有内容

{command}{text object or motion}

f,F => find the next character
t,T => find till
/,?   => search

the program print ("Hello, World!")

"hello world"

'hello world'

<p>hello world</p>

"hello world"

hello world
