      如何使用VIM的Help

       microee 2015-06-10

      很多時候在用到vim的命令的時候,都會去網(wǎng)上搜索,殊不知,如果熟練使用VIM的help,可以達到事半功倍的效果。

      下面介紹如何使用VIM的help:

       

      1.      在vim的一般模式中輸入:help可以進入vim的help界面


      這里面注意:

      Ctrl + ]      當(dāng)光標(biāo)在鏈接位置的時候,可以直接跳到鏈接內(nèi)容,鏈接一般是藍色。如:|:help|

      Ctrl + t      返回上次的頁面

      :q              退出help返回vim一般模式

       

      其中的表示,要在命令行里輸入“:helpi_<ESC>”,而不是輸入“:help i_”后,再去按下ESC鍵。

        

      2.在shell中輸入“vimtutor”可以進入vim的 tutor。

       

      其實,我感覺寫的最好的vim的初級入門還是這篇文章。這里摘出其中的summary供參考。

                                  LESSON 1 SUMMARY

       

       

        1.The cursor is moved using either the arrow keys or the hjkl keys.

        2.To start Vim from the shell prompt type: vim FILENAME <ENTER>

       

        3.To exit Vim type:      <ESC>  :q!   <ENTER>  to trash all changes.

                  OR type:          <ESC>  :wq  <ENTER>  to save the changes.

      NOTE: Pressing <ESC> will place youin Normal mode or will cancel

           an unwanted and partially completed command.
