A session in Termio is a real terminal running one thing — an agent, a dev server, or a plain shell. Here's the path from a fresh launch to a working setup.
Open a project
From the welcome screen, choose Open Project and pick a folder. Termio adds it to the sidebar and remembers it under Recent for next time. A project is just a working directory — the agents you launch inside it start there.
Launch an agent
With a project selected, start a new session and pick an agent — Claude Code, Codex, Gemini, or any other CLI you have installed. Termio opens it in a real terminal at the project root. You type into it exactly as you would in any terminal; the agent's TUI renders natively.
The sidebar shows the session's live status — working, idle, attention, or done. The sidebar guide explains each state; the one to watch for is attention, which means the agent is blocked on a prompt or a permission and needs you back.
Kick off a long run in one session, switch to another, and let the sidebar's attention state tell you the moment the first agent needs you back.
Split the window
Most real work wants more than one pane. Split the current pane to the right with
⌘D or downward with ⌘⇧D, then drop another session into the new pane — an
agent in one, your dev server in another, a shell in a third. Panes tile as a
tree, so you can nest splits into any layout.
Move focus between panes with ⌘⌥ + an arrow key, temporarily zoom the focused
pane to fill the window with ⌘⇧↩, and close it with ⌘W. Every shortcut is
rebindable — see Keyboard shortcuts.
A note on session lifetime
Sessions are live processes, not saved transcripts. When you quit Termio, the shells and agents exit — reopening the app starts fresh. The read-only session trace (see the Info pane) keeps a rendered record of what happened, but the running process itself doesn't survive a quit.
Quitting Termio ends every running agent and shell. Long agent runs don't survive an app restart — leave Termio open while they work.
