--- title: "Settings" description: "What lives in each section, and how the settings file works." --- ⌘ , opens Settings. There is a search box at the top that matches setting names *and* keywords, which is usually faster than remembering which section something is in. tty7 Settings ## The eight sections Theme, sync with system, typography, cursor, transparency, language. Shell and start directory, scrollback and scrolling, mouse, bell, per-pane history. Prompt features, selection & clipboard, keyboard (Option as Meta), links. Hosts, defaults, security, and every per-profile field. Hook installation per agent and per machine, and the CLI on PATH. Startup window, tab bar position and grouping, notifications, tray icon. Every shortcut, the tmux preset, the prefix. Version, update channel, and the updater. ## The settings file Everything the Settings window writes goes to one file: | | | |---|---| | macOS / Linux | `~/.config/tty7/config.json` | | Windows | `%APPDATA%\tty7\config.json` | Set `TTY7_CONFIG_DIR` to point the whole directory — config, themes, state — somewhere else. You can edit the file by hand; a handful of options exist only there. See the [configuration reference](/reference/configuration) for every key, its type, and its default. ### How it handles mistakes The file is written atomically, and read forgivingly: - **A missing key** means the default — you only have to write what you change. - **An out-of-range number** is clamped into its band, not rejected. - **An unrecognised enum value** falls back to the default with a log line, rather than failing the whole file. - **An unparseable file** is not overwritten. tty7 starts on defaults, keeps a copy at `config.json.corrupt`, and says so in the log. A UTF-8 BOM at the start of the file is tolerated, which matters if you edited it in a Windows editor. ## Language **Settings → Appearance → Language** switches the interface between English, 简体中文, and 日本語. The choice is explicit — the system language is never inferred — and CLI output stays English regardless, so agent and script integrations keep a stable surface. ```json { "gui_language": "zh-CN" } ```
