vim禁用鼠标

首先打开vim，进入末行模式使用scriptnames看看vim加载了哪些脚本：

:scriptnames
  1: /usr/local/share/vim/vim90/defaults.vim
  2: /usr/local/share/vim/vim90/filetype.vim
  3: /usr/local/share/vim/vim90/ftplugin.vim
  4: /usr/local/share/vim/vim90/indent.vim
  5: /usr/local/share/vim/vim90/syntax/syntax.vim
  6: /usr/local/share/vim/vim90/syntax/synload.vim
  7: /usr/local/share/vim/vim90/syntax/syncolor.vim
  8: /usr/local/share/vim/vim90/colors/lists/default.vim
  9: /usr/local/share/vim/vim90/plugin/getscriptPlugin.vim
 10: /usr/local/share/vim/vim90/plugin/gzip.vim
 11: /usr/local/share/vim/vim90/plugin/logiPat.vim
 12: /usr/local/share/vim/vim90/plugin/manpager.vim
 13: /usr/local/share/vim/vim90/plugin/matchparen.vim
 14: /usr/local/share/vim/vim90/plugin/netrwPlugin.vim
 15: /usr/local/share/vim/vim90/plugin/rrhelper.vim
 16: /usr/local/share/vim/vim90/plugin/spellfile.vim
 17: /usr/local/share/vim/vim90/plugin/tarPlugin.vim
 18: /usr/local/share/vim/vim90/plugin/tohtml.vim
 19: /usr/local/share/vim/vim90/plugin/vimballPlugin.vim
 20: /usr/local/share/vim/vim90/plugin/zipPlugin.vim
Press ENTER or type command to continue

然后进入/usr/share/vim/vim90/目录中，grep查找下含有set mouse的文件

grep -Ir 'set mouse'

在文本中定位到set mouse=a这行，注释

" 为注释符
if has('mouse')
  if &term =~ 'xterm'
"    set mouse=a
  else
    set mouse=nvi
  endif
endif
