Delete/yank into multiple registers at the same time?

Question

Is there a way to have y/d/c/x/s output into multiple registers at the same time - for example, "a as well as the system clipboard "+? I can do "aY"+Y obviously, and with Y it's alright (only one extra keystroke), but with d/x it wouldn't delete the same text, or if I were doing a complex motion like "ad?hello <CR> I wouldn't want to have to type that all over again. Can I make it so that something like "a"+Y does the same?

I'm using Neovim v0.4.4.

I haven't found some elegant way to do so bu you can create your own way to do so.

Code

1. First you can create somme key bindings (work on visual mode only).

xnoremap <Leader>y y:MultiRegister<Space> 
xnoremap <Leader>d d:MultiRegister<Space> 
xnoremap <Leader>c c:MultiRegister<Space> 
xnoremap <Leader>x x:MultiRegister<Space> 
xnoremap <Leader>s s:MultiRegister 

2. Secondly you can create your own custom command that will take the register name you gave:

command -nargs=+ MultiRegister call CopyToSelectedRegisters('<args>')

3. Finally you create a function that copy the selected area to the rest of the given registers:

function CopyToSelectedRegisters(SelectedRegisters)
    "Split the given registers by space
    let tab= split(a:SelectedRegisters)
    "for each register
    for register in tab 
        echo "let @".register."= @\""
        "Copy the content of the default register
        execute "let @".register."= @\""
    endfor
endfunction

Usage

1. In visual mode, select the area you want and press <leader> followed by y (or d,c,x,s).
2. You will be prompted in the command mode (bellow) with the MultiRegister command followed by a white space.
3. Enter the registers you want (for instance a b c +) and press enter.
4. Vim will do the copy to the designated registers (you can check it with :reg).

I hope this will help you
