l0ng-ai a723e71c9a fix(keybindings): give Alt+1..9 a way out, and stop one bad line resetting the file (#901)
Alt+1..9 are vim's tab keys, and tty7 takes all nine for Go to Tab.
Two things stood between the reporter and getting them back.

**Nothing in the app could leave an action unbound.** Backspace on a
Keybindings row that has recorded nothing *reset* the row — dropped the
override so the action gets its shipped chord back. On a row nobody had
overridden, which is every row the first time it is looked at, that is a
no-op: pressing it over Alt+1 left Alt+1 sitting exactly where it was,
which reads as the default restoring itself. `config.json` has spelled
"no chord" as `[]` since #868, but no gesture wrote it.

Backspace now writes that empty list. The row falls to `—` and grows the
**Reset** button every overridden row has, which is the way back to the
default. The capture hint names the key, and the docs say what it is for.

**A keybinding line serde could not read failed the whole `Config`.**
`keybindings` is a hand-edited map and was strict, so `"ActivateTab1":
null` — or a number, or an object — quarantined `config.json` and started
the app on built-in defaults. Every rebinding in the file then read as
its shipped default, and the next settings write persisted those
defaults over what the user had written. It now reads one entry at a
time, like every other hand-edited nested key here: the lines that name
a shortcut bind, a line that does not is logged and skipped.

Tests, each failing on the unfixed code:

- `ui::app::keybinding_gpui_tests::backspace_on_a_row_unbinds_the_action_rather_than_restoring_its_default`
- `core::config::tests::a_keybinding_line_that_cannot_be_read_does_not_take_the_config_with_it`

and `ui::keymap::gpui_tests::alt_digits_can_be_moved_off_the_tab_actions_for_good`
pins the merge and a save/reload round trip: a list replaces the shipped
Alt+1, `[]` leaves nothing, and neither comes back after a restart.

Fixes #901

tty7 with a tab sidebar of agent sessions across several repos, running Claude Code

Why

A background server owns your shells and panes — not the window. Everything below follows from that.

  • Performance — ~2× the throughput of Alacritty, Ghostty, or Kitty (benchmarks)
  • Persistent sessions — quit or reboot; your shells and supported agent sessions keep running, no tmux
  • Agent-aware — Claude Code, Codex & co.: status, notifications, and git context for every repo at once
  • Scriptable by agents — one agent opens a pane for another, hands off a task, waits, and reads the result, with or without the GUI running
  • Editor-grade input — suggestions, completion, highlighting, history search, with no plugin to install
  • Remote development — files, repos, panes, and git data stay on the remote machine, over a native SSH stack
  • Git beside the terminal — source control, diffs, and worktrees without leaving the window

Install

Native builds for macOS, Windows, and Linux on Releases:

macOS …-macos-arm64.dmg · …-x86_64.dmg drag into Applications
Windows …-setup.exe · portable ….zip
Linux …-x86_64.AppImage chmod +x and run — X11/Wayland libraries bundled

What's inside

Agent-aware per-pane detection (22 CLIs) · status dot · notifications · branch + diff · tray icon when input is needed · resume after reboot · tab sidebar grouped by repository
CLI + Skills bundled tty7 CLI · agent skill · run streams a command and exits with its code · split · send · wait --until free · capture
Editor-grade input ghost suggestions from history · explained tab completion · syntax highlighting · multi-line editing · click places the caret · ⌃ R fuzzy history
Window tabs & splits · ⌘ P palette · ⌘ F scrollback search · ⌘ J panel with process tree and listening ports · 13 themes, your own YAML, iTerm2 import · IME
Shell integration injected when a pane starts, nothing to install · prompt marks · working directory · exit codes · command-finished notifications · zsh, bash, fish, PowerShell, WSL, remote panes
Remote workspaces remote files, repos, changes, diffs, worktrees, tabs, and panes · reconnect from any client and continue where you left off
SSH native russh stack: profiles with keychain secrets · SFTP panel · port forwarding · jump hosts · one-time, unprivileged tty7-server install
Git panel follows the focused pane · stage, commit, amend, branch, push, stash · side-by-side or unified diffs · commit graph with cherry-pick, revert, and reset · a new worktree opens its own tab

Supported agents

Detection is free: brand avatar, branch + diff, tab title. Status takes one click under Settings → Agents to install that agent's hook, and brings the status dot, notifications, the tray icon, tty7 wait, and resume after a reboot. Fork needs both — the agent's own fork command, and the hook that tells tty7 which session to fork.

None of them are wrapped or proxied — the agent you start is the agent you get, in a normal PTY, with its own interface. An agent launched through a wrapper script can be mapped to one by name with agent_commands in config.json.

Documentation

Full documentation lives in docs/keyboard shortcuts · config.json · CLI reference. The agent-facing CLI interface is also documented in skills/tty7/SKILL.md.

Install the skill with:

npx skills add l0ng-ai/tty7    # install
npx skills update tty7         # update later
