如何将 vim 命令 :W 永久映射到 :w？

Question

有时在 vim 中，我在保存时按住 shift，最后执行:W. 如何将我的 vimrc 设置为识别:W为:w？

Answer 1

您不想映射一个键，而是创建一个行为与 w(rite) 相同的命令。只需将其写入 $HOME/.vimrc：

command W write

Answer 2

我也有一个“懒惰”的换档手指，所以我有许多命令别名：

" "Aliases" for commonly used commands+lazy shift finger:
command! -bar -nargs=* -complete=file -range=% -bang W         <line1>,<line2>write<bang> <args>

command! -bar -nargs=* -complete=file          -bang Make      make<bang> <args>

command! -bar                                        Messages  messages
command! -bar -nargs=+ -complete=file          -bang Source    source<bang> <args>

我有许多重复命令（例如W和 ）的原因Write是因为我有足够的用户定义命令，如果我不这样做，Vim 可能会抱怨用户命令的使用不明确。（看：:help user-cmd-ambiguous）
