为什么当我按下输入我的vim（gvim）在正常模式下显示^ M？

Question

there is a strange Phenomenon of my vim(gvim).
just as i said in title, when i press enter, it'll show ^M at lower right. and disappear after about 1sec, then it'll act as it should be. as if it's the first charactor of some "multi-charactor" command.

here are some lines in my vimrc.
au FileType * nnoremap <buffer> <CR> <C-]>
let mapleader = "\\<space>"
set encoding=utf-8
set fencs=utf-8,ucs-bom,shift-jis,gb18030,gbk,gb2312,cp936
set fileencodings=utf-8,ucs-bom,chinese
set ffs=unix,dos,mac

can someone tell me how to fix it?

thanks for Pinpin. but my problem occurs in normal mode.

thanks for any help :)

Answer 1

For internal reasons , <CM> is the same as <CR> (or <Enter> ). The reason that Vim briefly displays the key in the bottom right corner is that it is waiting for further keys (and you have :set showcmd ), because you have a mapping that begins with Enter .

:nmap <CR>

(or :nmap <Cm> ) will list it. To avoid the delay, you need to get rid of it / choose another key for it.
