Ctrl C和Ctrl [？]之间有什么区别？文档包含以下内容，我可以找到：
<Esc> or CTRL-[ End insert or Replace mode,go back to Normal mode. Finish
abbreviation.
Note: If your <Esc> key is hard to hit on your keyboard,train
yourself to use CTRL-[.
CTRL-C Quit insert mode,go back to Normal mode. Do not check for
abbreviations. Does not trigger the |InsertLeave| autocommand
event.
CTRL-C Interrupt current (search) command. Use CTRL-Break on
MS-DOS |dos-CTRL-Break|.
In Normal mode,any pending command is aborted.
似乎有一些不同意什么命令做什么。
Ctrl C是否也不会退出替换模式，以及缩写与待处理命令有何关系？
