Slim the READMEs to an index (why / install / what's inside / benchmarks); move feature details, keybindings, and performance notes to docs/features.md (en + zh-CN). New tagline: a terminal workbench — shells, sessions, SSH, coding agents. Sync the Cargo.toml description.

# 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
|
||
- **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
|
||
- **Command palette** <kbd>⌘ P</kbd> · scrollback search <kbd>⌘ F</kbd>
|
||
- **⌘-click links** · desktop notifications · copy on select (opt-in, Settings → Terminal → Clipboard)
|
||
- **Eight themes** · 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 (`claude --resume …`) on restore (`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
|
||
|
||
## 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
