vim一共有5种模式（先大概知道一下）

1. normal mode ： esc #用于浏览和编辑文件
2. insert mode ： esc i #对文件插入内容
3. replace mode： esc R #取代光标所指向的内容
4. visual mode： esc v #复制黏贴用
5. command-line esc : #文件保存，退出等操作。

4. To repeat a motion prepend it with a number:   2w
5. The format for a change command is:
            operator   [number]   motion
    where:
    operator - is what to do, such as  d  for delete
    [number] - is an optional count to repeat the motion
    motion   - moves over the text to operate on, such as  w (word),
                $ (to the end of line), etc.

6. To move to the start of the line use a zero:  0

7. To undo previous actions, type:           u  (lowercase u)
