From VIM to Tmux
There's a really good plugin tslime for sending text from VIM to another Tmux session/window/pane. In addition, sometimes it's super useful to map short cuts like this:
:vmap <buffer> \t <Plug>SendSelectionToTmux
In this example I'm mapping
\t for sending all visual selected text in VIM to Tmux.
