Targeting Specific Panes and Windows

With commands such as send-keys, you can specify not only the target session, but also the target window and pane. In the configuration file you created back in Chapter 2, ​Configuring tmux​, you specified a base-index of 1, meaning that your window numbering starts at 1. This base index doesn’t affect the panes, though, which is why you also set the pane-base-index to 1. In our case, we have two panes in our current setup, like the following example:

​ --------------------------

​ | |

​ | Pane 1 |

​ | |

​ --------------------------

​ | Pane 2 |

​ --------------------------

We have the Vim text editor open in Pane 1, and we want to send a command to Pane 2 that changes to our project directory. We target a pane using the format [session]:[window].[pane], so to target Pane 2, we’d use development:1.2. So, add this line to your script, and you’ll get exactly what you want:

​ tmux send-keys -t development:1.2 ​'cd ~/devproject'​ C-m

We’re almost there. Let’s finish up this configuration by adding a couple more windows to the session.
