I’d like to share one way to get the _evaluate line_ behavior of Juno/VSCode in Tmux.

Just a bit of context on why I’m trying to do that: today I found myself with three weeks to go without my laptop and very limited internet connection, but equipped with an Android tablet and a bluetooth keyboard, and I really don’t want to give up playing with Julia.

I normally use VSCode with its convenient _evaluate cell_ shortcut and its Remte SSH extension that allows me to work directly on a remote server.  
To reproduce a bit such setting, I installed Termux on the tablet, with which I can connect via ssh on the server. I can then attach to a Tmux session, where I have a splitted window: Neovim on the left to edit Julia files, and the Julia REPL on the right (see pic).

By adding the lines `bind j pasteb -t right` in my `.tmux.conf` and `set clipboard+=unnamedplus` in my `init.vim` (`.vimrc` for Vim), I can now copy some code in the Neovim pane on the left and send it to the REPL on the right by typing `C+b` and `j`.

I updated the last paragraph of the original post, since I misunderstood why my solution was working.

Also, I modified a bit my setting, since I was experiencing a very annoying delay when typing and editing files directly on the server. Now I open tmux locally, with neovim on the left pane to edit files in my local repository, while on the right pane I nest another tmux instance which run julia on the server.
