Another option is that the pattern matching included in the `.tmux.conf` is
not recognizing that Vim is active. To check that tmux is properly recognizing
Vim, use the provided Vim command `:TmuxNavigatorProcessList`. The output of
that command should be a list like:

```
Ss -zsh
S+ vim
S+ tmux
```

Vim is running in a tmux pane, use the provided Vim command `:TmuxNavigatorProcessList`. The output of
that command should look like the output from `ps -a|grep vim`.
If you encounter a different output please [open an issue][] with as much info
about your OS, Vim version, and tmux version as possible.
