说明：vim是一个很强大的编辑器，建议掌握基础使用方法即可，不要过于沉迷：vim有一套专门的语言来编写vim插件，vim也可以配置各种各样的插件打造成IDE，但是不建议在这上面花时间。把时间花在学习算法，学习编程，学习各种找工作实打实的硬技术上，而不是花在花里胡哨的地方（基本使用可以了解了解，装插件建议不要要搞了，pycharm、idea才是yyds）。
1: r !ls
2.i不移位（在前写入字符）
a右移一位（在前写入字符）
o另起一行（三者按Esc都向前移一位）
3.建议把CapsLK改为Esc
4.shift+a（行尾插入）
shift+i（行首插入）
shift+o（在上一行新加一行并写入）
5.~/.vim/vimrc为配置文件
5-1.noremap a b即vim中按a键相当于按了b键(nore意为非递归)
5-2.map S :wq（CR意为回车）
5-3.map s （nop意为no operation，即无效指令）
5-4.map R :source $MYVIMRC（加载vimrc文件）（这个我不能用）
5-5.syntax on 高亮
5-6.set number显示行号（set nu亦可）
5-7.set nonumber不显示行号(set nonu亦可)
5-8.set relativenumber(相对行号)
5-9.set cursorline（设置光标线）
5-10.set showcmd(右下角显示)
5-11.set wildmenu(命令模式下提示菜单)
5-12.set ai（自动缩进）
6.:vsp filename左右分屏<或vspit>（ctl+w跳屏）
:split filename上下分屏(:q 退出)
7.vim的一个规律 ，即动作加被执行者
7-1.x删除当前位置字符（与delete作用有相似之处）
7-2.“d” and number and “->” or “<-” 意为剪切或删除
7-3.dd删除当前光标所在行
7-4.p为粘贴操作，即paste
7-5.“y” and number and “->” or “<-” 意为复制（与d用法类似）
7-6.yy复制当前光标所在行
7-7.w调到下一个"单词首"，e跳到下一个"单词尾",跳到上一个"单词首"
7-8.“c” and number and “->” or “<-” 意为剪切或删除，同时进入写入模式
7-9.cw删除该单词，即change word（当你处于词首）
7-10.ciw删除该单词，即change in word（当你处于词中）
7-11.例7-10中w可以灵活去改变，例< ci" >,同理w换为y或d
7-12.0跳至行首，shift+0跳至段尾
7-13.f and charctor,即find，可以用来查找该行下一个出现的特定字符
7-14.同时f可以分别和d、y或c搭配使用，例< df: >
7-15. /charctor 来查找字符,n下一个，N上一个。
7-16.set hlsearch 查找高亮
set incseach 查找时高亮
exec “nohlsearch” 默认先执行"不高亮"(exec “x"即执行 :x)
7-17.set ignorecase 搜小写，大小写都出
set smartcase 搜大写，只出大写
7-18.let mapleader=” " 设置该建为空格
noremap :nohlsearch 设置空格加回车为取消高亮
7-19.:color 加 tab键 来切换颜色
注：终端输入vimtutor可以看关于vim详细教程
一.visual可视模式(三种模式与基础操作配合有神效)
1.普通可视模式(v进入)
2.可视行模式(大写V进入)
2-1.进入可视行模式然后“ 输入冒号接normal I接要往开头加的东西”
2-2.进入可视行模式然后“ 输入冒号接normal A接要往末尾加的东西”
2-3.ggVG全选(gg文首，G文尾)
3.可视块模式(ctl+v进入)
3-1.可视块模式下也可按G来提高效率
3-2.进入可视块模式后，shift+i来批量添加，c来批量替换（最后加ESC）
1.vim黏贴n编:np(例30p)
二、可视行模式下，批量执行命令
:norm $cs"’
:Tabularize /= 排版(等号排一排)
录制宏
函数跳转
coc 强大
