+A Zsh plugin to open files in a running Vim (or NeoVim) session, from an adjacent Tmux pane.
+
+When running either of these commands, they will find the first Tmux pane with Vim running in it, in the same window, and use `send-keys` to open the file there. Each command takes exactly one argument; the file path to open.
+
+## Available Commands
+
+* `tmux-vim-tabedit`
+* `tmux-vim-split`
+* `tmux-vim-vsplit`
