The current procedure for server maintenance is described in the above diagram. Users connect to the server in question via ssh. A shared command line / terminal (tmux session) is used for live, remote collaboration.

**Forest says:**

`tmux` is great except for it being an oldschool CLI program like `vim`, where it doesn't have any affordances for its essential functions. So it needs a good cheat sheet. But once the initial usability shock has been dispelled, its awesome because it allows multiple people to seamlessly share the same terminal and share/learn from each-other in real time.

`Ctrl + b` enters "tmux command mode" and once you are in that mode you can simply press the `d` key to disconnect from the tmux, or press `pageup` / `pagedown` to scroll the tmux.

There is no visual indication of whether you are in tmux command mode or not.

Tmux command mode is only good for one command, once you press another key, it will exit and return to normal shell interaction.


**Zico says:** 

`Ctrl+b [` to start scrollback, `q` to exit scrollback, `Ctrl+b ?` to see all the key combos.

`Ctrl+b n` to go to next pane
