12、】set hlsearch 启用类似Emacs的增量（incremental）搜索，搜索与输入同时进行【is】set incsearch 搜索内容不区分大小写【ic】set ignorecase 智能匹配，即小写全匹配，大小写混合则严格匹配【scs】set smartcase mouse=a 启动所有模式，会屏蔽鼠标的右键功能； mouse=v 让Vim在可视化模式下也可以使用右键粘贴set mouse=v 显示行号【nu】set number 显示光标所在列号【ru】set ruler 高亮当前行【cul】set cursorline 显示匹配的括号【sm】set showmatch 不显示

13、响铃【noeb】set noerrorbells 可视化铃声【vb】set visualbell 光标移动到buffer的顶部和底部时保持3行距离set scrolloff=3 高亮当前列【cuc】set cursorcolumn 启用List模式，用CTRL-I显示制表符，用$显示行结束符set list 显示当前的模式，FreeBSD下默认不显示【sc】set showcmd 启用自动缩进，和上一行的缩进保持一致【ai】set autoindentset smartindent 使用C语言的缩进风格【cin】set cindent 探测文件类型filetype on 为特定文件类型载入相关

14、缩进文件filetype indent on 设置F6为切换Paste模式的快捷键，便于从其他窗口向Vim中粘贴代码，GUI下的Vim可能无效【pt】set pastetoggle= 缩进和（软）制表符使用空格代替【et】set expandtab 设置制表符为4 个空格【ts】set tabstop=4 设置软制表符为4 个空格【sts】set softtabstop=4 设置缩进为4 个空格【sw】set shiftwidth=4 启用语法高亮【syn】syntax onfiletype plugin onfiletype indent on文件 dbutils_demo.zip3MB(8
