Three fixes for tty7's Tab completion: - Tab is no longer swallowed when the engine has no candidates: the locally edited line is handed off to the shell (text shipped raw, cursor walked back, Tab sent) and the local editor suspends until the next prompt cycle, so shell-native completion (compsys, fzf-tab, ...) answers instead. The handoff release keys off a new entered-prompt cycle counter rather than the raw Prompt-frame seq, so same-prompt redraws (PS1-embedded 133;B re-emissions) cannot re-engage the editor while zle still holds the handed-off text. - cd/pushd/popd/rmdir complete directories only in the no-signature path fallback; Fig 'folders' templates narrow signature slots the same way. Symlinks now classify by their target. - New tab_completion config field (default true) plus a Settings -> Terminal -> Keyboard toggle; when off every Tab goes to the shell.

# Features
|
||
|
||
<sub>English · [简体中文](features.zh-CN.md)</sub>
|
||
|
||
## Input
|
||
|
||
- **Ghost suggestions** — your history completes the whole line as you type; <kbd>→</kbd> to accept
|
||
- **Explained tab completion** — every flag and subcommand with its description, for ~100 common commands; when tty7 has nothing to offer the Tab falls through to your shell's own completion, and the whole feature can be turned off (Settings → Terminal → Keyboard, or `tab_completion` in `config.json`)
|
||
- **Syntax highlighting** — as you type, nothing to install
|
||
- **Fuzzy history search** — <kbd>⌃ R</kbd> shows what you ran, where, and whether it failed
|
||
- **History from day one** — your existing shell history works as-is and carries across sessions
|
||
- **Line editing** — click to place the caret, mouse selection, word motion, undo
|
||
- **Multi-line editing** — wrapped and multi-line commands edit in place; the grid shifts to keep the caret visible
|
||
|
||
## In the window
|
||
|
||
- **Tabs & splits** — always open in the current directory
|
||
- **Repo-grouped sidebar** — the left tab sidebar groups rows under a header per git repository, non-repo tabs in a trailing *Scratch* section; branch switches and in-repo `cd`s never move a row (`sidebar_grouping` in `config.json`: `repo` default, `none` for a flat list)
|
||
- **Command palette** <kbd>⌘ P</kbd> · scrollback search <kbd>⌘ F</kbd>
|
||
- **⌘-click links** · desktop notifications · copy on select (opt-in, Settings → Terminal → Clipboard)
|
||
- **Smart double-click selection** — double-click grabs the whole URL, file path, bracket/quote pair, or dictionary-segmented CJK word under the cursor; Shift-click extends a selection (toggle in Settings → Terminal → Mouse; word separators via `word_separators` in `config.json`)
|
||
- **Eight themes, plus your own** — YAML seed themes with solid, gradient, or image backgrounds; iTerm2 `.itermcolors` import; in-app color editor with a background-image picker
|
||
- **Sync with system** — Settings → Appearance; pick separate light and dark themes and tty7 follows the OS appearance live (`theme_follow_system`, `theme_preset_light` / `theme_preset_dark` in `config.json`)
|
||
- **Window opacity & blur** — Settings → Appearance → Window; applies to every theme, *Follow theme* returns to the theme's own `opacity` / `blur`
|
||
- **CJK / IME input**
|
||
|
||
## Coding agents
|
||
|
||
tty7 recognizes third-party coding agents running in a pane (Claude Code,
|
||
Codex, Gemini CLI, Aider, Amp, OpenCode, and ~10 more) and adds around them —
|
||
it never wraps or replaces the agent.
|
||
|
||
- **Brand avatars** — the tab chip / sidebar row shows which agent runs where; custom wrappers map in via `agent_commands` in `config.json`
|
||
- **Status dot** — working (blue) / needs your input (amber) / done (green), driven by agent-reported events over an OSC channel; run *Agent: Install Claude Code Hooks* from the palette to wire Claude Code up
|
||
- **Notifications** — "needs your permission…" the moment an agent blocks on you, and "finished after Ns" per turn, honoring your notification policy
|
||
- **Branch at a glance** — each sidebar row shows its pane's git branch and working-tree diff (`+N −M`), refreshed on `cd` and when a command finishes
|
||
- **Session resume** — panes lost to a reboot re-launch their agent conversation on restore, carrying the original launch flags (`claude --dangerously-skip-permissions --resume …`) (`restore_agent_sessions`, on by default)
|
||
- **Context feed** — palette commands send the current selection or the repo's `git diff` to the running agent as a ready-made prompt
|
||
- **Tray icon** — a system tray / menu bar item that flips to an attention state the moment any agent needs your input; its menu lists every agent pane (brand avatar + status dot, click to reveal), switches the notification policy, and offers *Quit and Stop Daemon* alongside the plain session-keeping quit (`show_tray_icon`, on by default)
|
||
|
||
## SSH
|
||
|
||
A native Rust SSH stack (russh) is the **only** path — profiles, credentials,
|
||
and SFTP without shelling out to `ssh`. There is no system-ssh compat mode.
|
||
|
||
- **QuickConnect** — type `user@host[:port]` in the palette and connect; IPv6 `[::1]:port` supported
|
||
- **Saved profiles** — full connection config with passwords / passphrases in the OS keychain, never on disk
|
||
- **`~/.ssh/config` aliases** — type one to connect (resolved natively — common fields, best-effort — over russh), or import them as profiles in Settings
|
||
- **GUI auth** — in-pane sheets for password, key passphrase, 2FA, and host-key confirmation (new vs. changed)
|
||
- **Built-in SFTP** — a slide-in file panel: browse, upload / download, rename / delete / chmod, drag to Finder
|
||
- **Port forwarding** — Local / Remote / Dynamic, preconfigured or added live, plus ⌘-click `localhost:PORT` to auto-forward
|
||
- **Jump hosts & proxies** — multi-hop via profile references or `ProxyJump`, ProxyCommand, SOCKS5 / HTTP
|
||
|
||
| Entry point | Connects via |
|
||
|---|---|
|
||
| Saved profiles · QuickConnect · typed `user@host[:port]` | Native russh — SFTP · keychain · GUI auth · L/R/D forwards |
|
||
| `~/.ssh/config` aliases | Resolved natively, then russh (`Match`/canonicalize/GSSAPI unsupported — no fallback) |
|
||
|
||
## Keybindings
|
||
|
||
Keys are shown in macOS notation — on Windows and Linux, read <kbd>⌘</kbd> as
|
||
<kbd>Ctrl</kbd>. The essentials:
|
||
|
||
| | |
|
||
|---|---|
|
||
| <kbd>⌘ T</kbd> · <kbd>⌘ W</kbd> · <kbd>⌘ ⇧ T</kbd> | new tab · close tab · reopen closed tab |
|
||
| <kbd>⌘ 1</kbd>…<kbd>⌘ 9</kbd> · <kbd>⌃ ⇥</kbd> · <kbd>⌃ ⇧ ⇥</kbd> | jump to tab 1–9 · next tab · previous tab |
|
||
| <kbd>⌘ D</kbd> · <kbd>⌘ ⇧ D</kbd> | split right · split down |
|
||
| <kbd>⌘ ]</kbd> · <kbd>⌘ [</kbd> | next pane · previous pane |
|
||
| <kbd>⌘ ⌥ ←→↑↓</kbd> | focus the pane in that direction |
|
||
| <kbd>⌘ ⏎</kbd> · <kbd>⌘ ⇧ ⏎</kbd> | toggle fullscreen · maximize / restore the pane |
|
||
| <kbd>⌘ K</kbd> | clear the screen and scrollback |
|
||
| <kbd>⌘ P</kbd> | command palette |
|
||
| <kbd>⌘ F</kbd> | search the scrollback |
|
||
| <kbd>⌃ R</kbd> | fuzzy-search shell history |
|
||
| <kbd>⌘ +</kbd> · <kbd>⌘ −</kbd> · <kbd>⌘ 0</kbd> | font size up · down · reset |
|
||
|
||
**Settings → Keybindings** (<kbd>⌘ ,</kbd>) lists every shortcut. Click one,
|
||
press the new keys (<kbd>Esc</kbd> cancels, <kbd>Backspace</kbd> resets to
|
||
default), and it takes effect immediately. Pane resize and swap have no default
|
||
keys — bind them here or run them from the command palette.
|
||
|
||
**tmux preset** — remaps pane/tab actions onto a prefix (default <kbd>⌃ B</kbd>):
|
||
<kbd>⌃ B</kbd> <kbd>C</kbd> opens a tab, <kbd>⌃ B</kbd> <kbd>%</kbd> splits,
|
||
<kbd>⌃ B</kbd> then an arrow moves focus. A bare prefix reaches the shell after
|
||
a brief pause; `prefix` + an unbound key passes straight through.
|
||
|
||
## Performance notes
|
||
|
||
- The PTY is read at device speed and parsed in large batches, off the render path
|
||
- Hot paths are lock-free — a big `cat` never waits on drawing
|
||
- The daemon buffers up to 16 MiB ahead of the window before backpressure applies
