vim 注释代码

[!question] 问题

今天老师教了使用 ,cu/,cc 注释代码，但貌似我的 vim 没有对应的配置没法使用，所以在 stackoverflow 这了这个问题 What's a quick way to comment/uncomment lines in Vim? - Stack Overflow

To comment out blocks in vim: ​

• press Esc (to leave editing or other mode)
• hit ctrl+v (visual block mode)
• use the ↑/↓ arrow keys to select lines you want (it won't highlight everything - it's OK!)
• Shift+i (capital I)
• insert the text you want, e.g. %
• press EscEsc

To uncomment blocks in vim: ​

• press Esc (to leave editing or other mode)

• hit ctrl+v (visual block mode)

• use the ↑/↓ arrow keys to select the lines to uncomment.

  If you want to select multiple characters, use one or combine these methods:

  • use the left/right arrow keys to select more text
  • to select chunks of text use shift + ←/→ arrow key
  • you can repeatedly push the delete keys below, like a regular delete button

• press d or x to delete characters, repeatedly if necessary

StackOverflow 上也有 ,cc/,cu 的配置文件：

" Commenting blocks of code.
augroup commenting_blocks_of_code
  autocmd!
  autocmd FileType c,cpp,java,scala let b:comment_leader = '// '
  autocmd FileType sh,ruby,python   let b:comment_leader = '# '
  autocmd FileType conf,fstab       let b:comment_leader = '# '
  autocmd FileType tex              let b:comment_leader = '% '
  autocmd FileType mail             let b:comment_leader = '> '
  autocmd FileType vim              let b:comment_leader = '" '
augroup END
noremap <silent> ,cc :<C-B>silent <C-E>s/^/<C-R>=escape(b:comment_leader,'\/')<CR>/<CR>:nohlsearch<CR>
noremap <silent> ,cu :<C-B>silent <C-E>s/^\V<C-R>=escape(b:comment_leader,'\/')<CR>//e<CR>:nohlsearch<CR>

我没有试验过。

我是 VSCode + Vim，还瞎折腾什么😂。直接 Ctrl - / 在 Vim 模式下是可以用的，另外我把 Ctrl绑定到了 Win 按键（用Sharpkeys）。
