制图 <C-left> 和 <S-left> 在Vim

Question

I've been trying to get Vim to behave a little more like ACE to no avail.

In particular, I've been trying to get Vim to accept CTRL + LEFT in insert mode as a mapping for ESC, v, B , and SHIFT + LEFT in visual mode as a mapping for B , for example:

" in my ~/.vimrc:
inoremap <C-LEFT> <ESC> v B
vnoremap <S-LEFT> B

But these bindings seem to fail. To be clear, I get an error that says

E388: Couldn't find definition

when I try the CTRL + LEFT mapping:

What am I doing wrong?

Answer 1

You need to drop the spaces between the individual keys; whitespace only separates the left-hand side from the right-hand side:

:inoremap <C-LEFT> <ESC>vB

<Space> in normal mode is a command that moves the cursor to the right; that would interfere with the mapping.

You need to check that no other configuration / plugin remaps your left-hand side later:

:verbose imap <C-LEFT>
:verbose vmap <S-LEFT>

Also note that inside the terminal, combinations of modifier keys (like Shift and Ctrl ) and other keys may not work; this shouldn't be a problem in GVIM, though.
