我使用的机器是 mac，这是我的 vimrc 文件 1 " Configuration file for vim 2 set modelines=0 " CVE-2007-2438 3 4 " Normally we use vim-extensions. If you want true vi-compatibility 5 " remove change the following statements 6 set nocompatible " Use Vim defaults instead of 100% vi compatibility 7 set backspace=2 " more powerful backspacing 8 9 " Don't write backup file if vim is being called by "crontab -e" 10 au BufWrite /private/tmp/crontab.* set nowritebackup 11 " Don't write backup file if vim is being called by "chpass" 12 au BufWrite /private/etc/pw.* set nowritebackup 13 set number 14 imap jj 15 set shiftwidth=4 16 set tabstop=2 17 18 execute pathogen#infect() 19 map :NERDTreeToggle ~
现在我打 ctrl+space 会由 insert 转换到 normal 模式，我现在想取消这个 map 应该怎么做
