Answer 2

I always use another better way:

augroup PASTETOGGLE
  autocmd! InsertEnter * setlocal paste
  autocmd! InsertLeave * setlocal nopaste
augroup END

This way you don’t need to set anything at all when pasting in insert mode, and there is no need for alternative key combinations.

Supplement: I forgot to mention the side effects of this method. It will cause the options such as 'autoindent' and 'smartindent' in insert mode to be reset, so it is equivalent to canceling automatic indentation, so please use it selectively.

Answer 3

Use vi to paste the code and it’s OK

Answer 4

You can also do this “+p to paste;
For convenience, I made a mapping nnoremap <leader>p "+p;
Type :reg to see what's held in the register;
Select some characters first, and then ”+y you can copy the selected part to the system clipboard;
