如何在Vim中的映射中使用+（或=）键？

Question

I wanted to remap (for normal mode) Ctrl + a to Ctrl + = and Ctrl + x to Ctrl + - but it didn't work.

Is there another way to write this?

Answer 1

I had a problem using and because my shell uses those to resize my window and font size. I was able to map '+' and '-' to the commands so pressing them in normal mode incremented and decremented values.

map + <C-a>
map - <C-x>

Is that what you were trying to accomplish? I don't know if that will work for you, since they probably have different uses that I don't use.

You could also use a mapleader instead of control to do this and not mess with any default uses:

let mapleader=","
map <Leader>+ <C-a>
map <Leader>- <C-x>

Instead of C-+ and C-- , you would use ,+ and ,- .

Answer 2

我不确定Ctrl + = ，但对于Ctrl + - ，请尝试使用Ctrl + _ （用下划线替换连字符）。

Answer 3

Works for me.

map <C-a> <C-=>
map <C-=> :echo 'ken'<CR>

map <C-x> <C-->
map <C--> :echo 'barbie'<CR>

Then <Ca> should echo ken and <C--> should echo barbie
