我无法在Vim中使用引导键。我已经进行了一段时间的故障排除。
我已经做过的事情：
let mapleader = ';'
source $VIMRUNTIME/vimrc_example.vim
source $VIMRUNTIME/mswin.vim
set diffexpr=MyDiff()
function MyDiff()
let opt = '-a --binary '
if &diffopt =~ 'icase' | let opt = opt . '-i ' | endif
if &diffopt =~ 'iwhite' | let opt = opt . '-b ' | endif
let arg1 = v:fname_in
if arg1 =~ ' ' | let arg1 = '"' . arg1 . '"' | endif
let arg1 = substitute(arg1, '!', '\!', 'g')
let arg2 = v:fname_new
if arg2 =~ ' ' | let arg2 = '"' . arg2 . '"' | endif
let arg2 = substitute(arg2, '!', '\!', 'g')
let arg3 = v:fname_out
if arg3 =~ ' ' | let arg3 = '"' . arg3 . '"' | endif
let arg3 = substitute(arg3, '!', '\!', 'g')
if $VIMRUNTIME =~ ' '
if &sh =~ '\<cmd'
if empty(&shellxquote)
let l:shxq_sav = ''
set shellxquote&
endif
let cmd = '"' . $VIMRUNTIME . '\diff"'
else
let cmd = substitute($VIMRUNTIME, ' ', '" ', '') . '\diff"'
endif
else
let cmd = $VIMRUNTIME . '\diff'
endif
let cmd = substitute(cmd, '!', '\!', 'g')
silent execute '!' . cmd . ' ' . opt . arg1 . ' ' . arg2 . ' > ' . arg3
if exists('l:shxq_sav')
let &shellxquote=l:shxq_sav
endif
endfunction

在右下角的vim屏幕上应该有一个\（想在vimtex中使用\ ll），但是它只是发出哔声。我可以在CMD-Window或vim插入模式下使用\，但不能在“普通” -vim窗口（ESC，ESC）中使用它
答案 0 :(得分：0)
尝试像以前尝试的那样将引导键映射到另一个键，但是将let mapleader = ';'放在_vimrc的第一行（而不是最后一行），因为<Leader>定义map / noremap时，<LocalLeader>和_vimrc会展开。通过在最后设置领导者，将导致以前完成的所有映射（在插件中以及在mswin.vim和vimrc_example.vim中）都无法与新领导者一起使用。
所以let mapleader = ';'
source $VIMRUNTIME/vimrc_example.vim
source $VIMRUNTIME/mswin.vim
set diffexpr=MyDiff()
function MyDiff()
let opt = '-a --binary '
...
...
将是：
<ul>
<li>Parent
<ul>
<li>
<ul>
<li>Child</li>
--add new child node (how to return this new child node model)
</ul>
</li>
--add new child node (how to return this new child node model)
</ul>
