Thank you John for your answer! I appreciate your answer even more, that you took the time for it in Easter Holidays. (<- sounds not like a good English idiom? Probably it's a French expression?).

Something I am doing wrong.

1. I put two lines in my .vimrc file:
a) vnoremap // y/<C-R>"<CR>
b) vnoremap <expr> // 'y/\V'.escape(@",'\').'<CR>'

I visual select the lines in my file to edit:


\begin{center}
\textcolor{mygray}{\large W}
\end{center}

I enter //

Result: /\V\\begin{center} in the status (command?) line. That means this is the first line from my visual selection only. Did I do something wrong?

What I need is the following:

I visual select the lines to search for, I hit a command (which one?), and in the status line I have my search pattern automatically with escaped special characters like follows:

:s/\\begin\{center\}\n \\textcolor\{mygray\}\{\\large W\}\n\\end\{center\}\n//

So that I can edit the search pattern in the status line like follows:

:%s/\\begin\{center\}(\s+)\\textcolor\{mygray\}\{\\large ([^}]+)\}\s+\\end\{center}\s+/$1\\vimcode{$2}\n/g

Would this be possible?

Best greetings to all
