> Concepts for libtmux.

Understand captured queries, object identities, and operations.

- [Read values, execute explicitly](https://libtmux.org/en/elixir/latest/concepts/mental-model/): Hold one captured graph for several decisions and run a command when you need another.
- [Captured tmux state](https://libtmux.org/en/elixir/latest/concepts/observations/): Capture an immutable snapshot of an existing server and read it without further commands.
