Vim 功能键突然改变了它们的映射

Question

今天我的功能键都改变了它们的行为。

例如，

F1 不再打开帮助，但等同于在正常模式下键入 OP。也就是说，它在当前行上方打开一个新行，进入插入模式并键入 'P'。正如您在我的 .vimrc 中看到的那样，我唯一的功能键映射是 map <f2> :set rnu!<cr>，直到今天它都运行良好。

F2 现在键入 <F2> 并进入替换模式，然后在退出替换模式之前按 <esc> 键入另一个 <F2>。

F3 现在在上面打开一个新行，进入插入模式并输入 'P'

F5一次改变5个连续字符的大小写

F6到F10和F5功能类似，只是改变字符个数的大小写。

编辑：在插入模式下键入 <c-v><f1> <c-v><f2>... 等显示它们现在映射到 ^[OP ^[OR ^[OQ 等。 .但我仍然不知道如何或为什么

功能键在其他程序（gedit、firefox 等）中按预期工作，在不同的终端中打开 vim 也没有什么不同，这让我相信它纯粹是 vim问题。

这非常令人沮丧，因为我不知道从哪里开始解决这个问题，而且到目前为止我在网上找不到任何类似的问题。

重启电脑vim也没有效果..

Behviour 是由于我的 .vimrc 中的 <esc> 键映射，这似乎是不可取的。映射本身 map <c-[> <esc> 也是多余的，因为 <c-[> 默认情况下作为 <esc> 工作，至少在 US/GB 键盘上是这样。

在没有插件的情况下打开 vim 或运行 vim -u NONE 的 .vimrc 有助于确定问题。
