The terminal
Lights Out is a terminal made for running AI agents: everything you need is on screen, and everything else is one shortcut away.

Rooms
A room is its own set of tabs, for example one room per project. Click a room to switch to it; its tabs and agents come with it. Agents in other rooms keep running.
- New room: click + room or press Ctrl+Shift+N.
- Rename or close a room: open actions. Closing a room stops its agents.

- Drag to select text; it's copied with Ctrl+Shift+C.
- Right-click for copy, paste, split and close.

Alerts
When an agent finishes or needs your answer, Lights Out shows a popup and plays a short sound (Windows and Mac). Ctrl+Shift+J jumps straight to the agent that needs you.
Lights Out recognises common questions by itself. If one of your tools asks in its own words, add the phrase to needs_you in the settings.
Closing the window
Closing the window doesn't stop your agents: they keep running, and lightsout brings the window back. Quit in actions stops everything. Your tabs come back the next time you open Lights Out.
