为什么nnoremap不能与CtrlP一起使用，nmap确实有效？ - VIM

Question

I have this in my .vimrc

nnoremap <leader>p :CtrlP<CR><C-\>w

I change all nmap to nnoremap in my .vimrc and everything works fine except this one:

nnoremap <leader>p :CtrlP<CR><C-\>w

With nmap <leader>p :CtrlP<CR><C-\\>w it does automatically insert word into CtrlP and with nnoremap it doesn't, I get blank field, like I just pressed Ctrl-P .

Why it doesn't work with nnoremap ?

Answer 1

When you create a mapping with nnoremap , it does not consider your prior mappings when resolving what to do. In other words, if you had previously mapped any of these:

<CR>
<C-\>
w

Then those maps would be ignored in your <leader>p mapping, and instead the default action of those keystrokes would be used.

As far as I know, <C-\\> has no default action, so I would suspect you have mapped it (or you are relying on a mapping that another plugin has added), but that mapping is not being taken into account here.
