l0ng-aiandl0ng-ai 707fd1867b docs: add a Mintlify documentation site (#478)
38 pages under docs/, written against the source rather than the README:
config keys and their clamps from core::config, default keybindings from
ui::keymap, every CLI verb and flag from tty7-cli, agent aliases and
hook/fork/resume support from core::cli_agent, and Settings paths taken
from the actual en-US strings.

docs/features.md and its zh-CN translation are retired — everything in
them now lives in a page of its own, plus the two things they carried
that nothing else did (IME input, the performance notes). README and
README.zh-CN point at docs/ instead.

Screenshots and videos are placeholders for now: docs/images/placeholder.svg
with a caption naming what each shot should be.

title: "Keybindings"
description: "Rebinding anything, chord sequences, and the tmux preset."

**Settings → Keybindings** (<kbd>⌘ ,</kbd>) lists every shortcut in the app,
grouped the same way the command palette is.
## Rebinding
Click a shortcut and press the new keys. It saves after a brief pause.
| | |
|---|---|
| Press keys | Set the binding |
| Press more keys | Chain a sequence — <kbd>⌃ B</kbd> then <kbd>X</kbd> |
| <kbd>Esc</kbd> | Cancel |
| <kbd>⌫</kbd> | Remove the last key — or, pressed first, reset the shortcut to its default |
**Restore all defaults** at the bottom undoes every rebinding at once. There is
no undo for that one.

## Actions with no default key
Some actions ship deliberately unbound, because there is no obvious key left to
take: pane resize and swap, workspace selection, most git commands, SFTP, and
the panel tabs. They are all in the command palette, and all bindable here.
## Editing `config.json` instead
```json
{
"keybindings": {
"SplitRight": "cmd-d",
"ResizePaneLeft": "ctrl-alt-left",
"ToggleSftp": "cmd-shift-u"
}
}
```
The syntax is modifiers joined by `-`, then the key. Chords are separated by a
space.
| Token | Means |
|---|---|
| `secondary` | <kbd>⌘</kbd> on macOS, <kbd>Ctrl</kbd> elsewhere |
| `cmd` · `ctrl` · `alt` · `shift` | Literal modifiers |
| `ctrl-b n` | A two-key sequence |
An unknown action name or an invalid keystroke is skipped with a warning in the
log rather than breaking the rest of your bindings.
The full action list is on the [keyboard shortcuts](/reference/keyboard-shortcuts)
page.
## The tmux preset
**Settings → Keybindings → Preset → tmux** remaps pane and tab actions onto a
prefix — <kbd>⌃ B</kbd> by default, changeable in the **Prefix** field beside
it.
| | |
|---|---|
| <kbd>⌃ B</kbd> <kbd>C</kbd> · <kbd>X</kbd> | New tab · close tab |
| <kbd>⌃ B</kbd> <kbd>%</kbd> · <kbd>"</kbd> | Split right · split down |
| <kbd>⌃ B</kbd> <kbd>←→↑↓</kbd> | Move focus |
| <kbd>⌃ B</kbd> <kbd>⌃ ←→↑↓</kbd> | Resize the pane |
| <kbd>⌃ B</kbd> <kbd>O</kbd> · <kbd>;</kbd> | Next pane · previous pane |
| <kbd>⌃ B</kbd> <kbd>&#123;</kbd> · <kbd>&#125;</kbd> | Swap with the previous · next pane |
| <kbd>⌃ B</kbd> <kbd>Z</kbd> | Zoom the pane |
| <kbd>⌃ B</kbd> <kbd>N</kbd> · <kbd>P</kbd> | Next tab · previous tab |
| <kbd>⌃ B</kbd> <kbd>1</kbd>…<kbd>9</kbd> | Jump to a tab |
Two details that make it livable:
- A **bare prefix** reaches the shell after about a second, so <kbd>⌃ B</kbd>
still works as "back one character" when you meant it.
- **Prefix plus an unbound key** is passed straight through to the terminal, so
a tmux binding you did not remap still lands in whatever is running.
## Some non-obvious defaults
| | |
|---|---|
| <kbd>⇧ ⏎</kbd> · <kbd>⌥ ⏎</kbd> | Insert a newline at the prompt instead of submitting (`InsertNewline`) |
| <kbd>⌘ ⇧ ⏎</kbd> | Zoom the focused pane |
| <kbd>⌘ ⇧ E</kbd> | Toggle the code panel |
| <kbd>⌘ ⇧ R</kbd> | Restart the SSH session in this pane |
| <kbd>⌘ ⇧ O</kbd> | Workspace switcher |
| <kbd>⌘ ⇧ N</kbd> | New workspace |
