为了节省 Vim 的时间,我想出了一个主意。在正常模式和插入模式下将 :w 键绑定映射到 Esc。但是,它仅在插入模式下有效,而在正常模式下,当我打开一个新文件时,事情会变得一团糟。这是我在 .vimrc 中添加的内容:

:inoremap <Esc> <Esc>:w<CR>
:nnoremap <Esc> :w<CR>

正如我单独说的第一个命令,工作正常。但是添加第二个命令,特别是当我打开一个新文件时,键会被弄乱。例如,虽然我在 .vimrc 中明确添加了:

map <up> <nop>
map <down> <nop>
map <left> <nop>
map <right> <nop>

通过添加正常模式的第二个命令,按向上向下向左或向右键导致进入插入模式并添加ABC D。

你能帮我实现我的想法吗?

关于Vim FAQ 10.9 的信息可能有用

10.9. When I use my arrow keys, Vim changes modes, inserts weird characters
     in my document but doesn't move the cursor properly. What's going on?

There are a couple of things that could be going on: either you are using
Vim over a slow connection or Vim doesn't understand the key sequence that
your keyboard is generating.

If you are working over a slow connection (such as a 2400 bps modem), you
can try to set the 'timeout' or 'ttimeout' option. These options, combined
with the 'timeoutlen' and 'ttimeoutlen' options, may fix the problem.

The preceding procedure will not work correctly if your terminal sends key
codes that Vim does not understand. In this situation, your best option is
to map your key sequence to a matching cursor movement command and save
these mappings in a file. You can then ":source" the file whenever you work
from that terminal.

For more information, read 

    |'timeout'|
    |'ttimeout'|
    |'timeoutlen'|
    |'ttimeoutlen'|
    |:map|
    |vt100-cursor-keys|

来自:h vt100-cursor-keys

Other terminals (e.g., vt100 and xterm) have cursor keys that send <Esc>OA,
<Esc>OB, etc. ...

因此,您可能nnoremap会导致Esc箭头键序列上的 保存文件,而其余字符将被单独解释,因此A正在进入插入模式。

您可以考虑使用 option 'autowriteall',或使用不同的映射来保存文件;这些定义在$VIMRUNTIME\mswin.vim

" Use CTRL-S for saving, also in Insert mode
noremap <C-S>       :update<CR>
vnoremap <C-S>      <C-C>:update<CR>
inoremap <C-S>      <C-O>:update<CR>

:update命令类似于:w,但仅在文件已被修改时才写入。

此外,您可以使用

autocmd InsertLeave * write
