Recently there was an add-on to NeoVim which allows opening terminal in a vim buffer. This has appealing possibilities to send text from one vim window to another replicating, for example, a REPL like behavior.
In the past I was using tmux for this kind of configuration. However now I would like to try it out using only NeoVim.
My question is - how can I send a block of text from one vim split to another? Or maybe rather - how can I automate the sequence of selecting text, yanking it, changing splits and then pasting?
