Terminal

C2 has an embedded terminal so you can run commands next to the agent. It lives in the side dock — open it with Mod+J, or the panel button in the header and pick the Terminal tab. The dock sits beside the document rather than under it, so opening a terminal doesn't shrink the prompt you're writing.

It's a real PTY: C2 spawns your login shell ($SHELL) through a pseudo-terminal and streams its output to an xterm.js view. Keystrokes go back to the shell, and the terminal resizes with the panel.

The terminal opens in the session's working directory, so it's already where the agent is working — handy for running tests, checking git status, or inspecting what a turn changed.

Multiple terminals

Use the ＋ tab to open more terminals and click the tabs to switch. All of them stay mounted, so switching away doesn't kill a running shell.

tmux — persistent, attachable terminals

Tick tmux in the terminal header and C2 runs each terminal inside a named tmux session (codetwo-<session>-<n>) using attach-or-create. That buys you two things:

• The shell survives app restarts — reopen the terminal and you're back where you were.

• You can attach from a real terminal:

  tmux attach -t codetwo-<session>-1

If tmux isn't installed the toggle simply falls back to a plain login shell.

TIP

Under the hood the PTY is managed by the Rust core, and output reaches the renderer through the desktop sidecar event stream — the same PTY machinery is available to the remote server too.
