Is there a command to yank the contents of the current buffer? I cant seem to find anything in the neovim docs or via an internet search. I appreciate I can do gg to jump to the top then v for visual mode and then G to select the whole buffer contents, y to yank the contents into the clipboard... am I missing a simpler command sequence or plugin?

Recently, I’ve been trying to use .md files for Clerk notebooks instead of .clj, since I sometimes have a lot more Markdown text to write than code and editing Markdown is (of course) much nicer in a dedicated buffer than in Clojure comments. However, editing Clojure code without my structural editing tools and without evaluation is very painful, so I was looking for a solution that works similar to how you can edit OrgMode code blocks in Emacs in a temporary buffer that has the correct major mode for the language. I found vim-fancy (https://github.com/vitalk/vim-fancy/), which does exactly what I need, but sometimes crashes Neovim when I evaluate forms that print to the console or when I open popup-buffers, etc. But if I am careful it works quite well for basic stuff. Timeshift (https://github.com/hkupty/timeshift.vim) does the same thing, but I couldn’t get it to work (somehow it doesn’t parse the filetype correctly in my code blocks). Just wanted to ask around if someone knows about another plugin or a different solution.
