I use NERDTree, in vim and there is a very useful shortcut
Ctrl+w+wis used to switch horizontally, but I think it"s too troublesome. I want to set another shortcut for this key combination, such as
.Ctrl+Alt+Left
I don"t know how to configure it in .vimrc
if you say Left is a direction key, vimer had better not use the direction key.
my shortcut key to switch windows is ctrl + h, j, k, l. They correspond to switching to the left, down, up, and right, respectively. By the way, I mapped < cmurw > w to < cmurw >
.nnoremap <c-w> <c-w>w
nnoremap <c-j> <c-w>j
nnoremap <c-h> <c-w>h
nnoremap <c-k> <c-w>k
nnoremap <c-l> <c-w>l
