How can I use registers in CtrlP?

ctrlp, vim

Solution

it looks like you need `<c-\>` it opens a console dialog to paste `<cword>`, `<cfile>`, the content of the search register, the last visual selection, the clipboard or any register into the prompt.

Problem

I want to use vim registers in CtrlP input form, like `<C-r>"`. `<C-r>` is used by `ToggleRegex()` by default. So I configure CtrlP with g:ctrlp_prompt_mappings. like that, ``` let g:ctrlp_prompt_mappings = { \ 'ToggleRegex()': ['<C-g>'], \} ``` Then it seems to make effect, but error occur with pressing `<C-r>`. ``` E21: Cannot make changes, 'modifiable' is off ``` How can I do that?
