每当我用 vim 打开一个文件时，vim 会话2c都会自动/以编程方式“按下”开始。这意味着，如果我开始尝试通过按下 向下移动文件j，则会执行该操作2cj，这意味着两行将被删除。因此，每次我启动 vim 会话时，我都必须<esc>先按下 才能正常继续。这变得很乏味，并且会破坏我的 vim 肌肉记忆。
我多次查看过我的 .vimrc 文件，但还是不明白是什么原因导致的。也许这和 .vimrc 文件没有任何关系。不过，这是我的 .vimrc 文件：

我并不指望任何人都会读完所有这些内容，但我真的不确定其中的哪一部分可能会导致这个问题。
是否有人知道什么原因导致这些按键在 vim 会话开始时自动添加？
编辑：
我在 Mac 上安装了 OS X 10.8，我使用苹果的默认终端程序。我也在使用 oh-my-zsh，但我认为这不会有什么影响。
答案1
这可能是来自终端的 termresponse 序列。尝试启动 vim 作为
$ vim --cmd 'set t_RV='
您也可以尝试在 vim 中执行此操作：
:echo v:termresponse
看看它是否包含2c。
当我在后台的服务器上从台式机上的终端仿真器运行 vim 时，我曾经遇到过类似的问题。termresponse 序列从终端返回到 vim 需要很长时间，以至于部分序列被接受为好像来自键盘。我最终禁用了 termresponse 查询，并在 ~/.vimrc 中“手动”设置了“ttymouse”。请参阅
:help 'ttymouse'
:help t_RV
:help v:termresponse
编辑
我从该系统中找到了 ~/.vimrc 文件。下面是我修复该问题时使用的内容。
set t_RV= ttymouse=xterm2 " Temporary (?) kludge to avoid problems
" when starting vim with "-c grep
" something" where the termresponse puts
" vim into insert mode. [2006-01-18]
" 'ttymouse' must be set to "xterm2"
" manually to get the mouse to drag window
" borders because vim needs the
" termresponse to set it correctly
" automatically.
