如何使用VIM的Help
很多時候在用到vim的命令的時候，都會去網上搜索，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+]???? 在光標在鏈接位置的時候，可以直接跳到光標處
: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。
?
?
?
4.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。
