dsh-composer-keys ⌨️
Keyboard shortcuts for the DeepSeek Harness (DSH) Web chat composer.
中文文档：简体中文
Type faster, navigate history with pure keyboard. No mouse needed.
✨ Features
| Shortcut | Action |
|---|---|
| ↑ Arrow Up | Fill the composer with the previous user message from history |
| ↓ Arrow Down | Move to the next user message; at the end, restore your original input |
| Ctrl+C | Clear the composer when no text is selected (avoids conflict with Copy) |
Behavior details
- History cycling follows shell-style semantics: press ↑ to walk backwards through your previously sent messages; press ↓ to walk forward again; at the newest end it restores whatever you had typed before you started navigating.
- Ctrl+C only clears when the composer has content and no text is selected — if you have selected text, the browser's native Copy takes precedence.
- Uses Ctrl+C only, identical on Windows and macOS (on macOS,
Cmd+Cstays the system Copy).
📦 Install

After installing, restart the DSH Web GUI and reload the page.
🧩 How it works
A client-only plugin. It registers an invisible component in the
conversation.composer.dock slot (the additive, non-destructive input-region seat),
which attaches a keydown listener on document and intercepts shortcuts only while
the composer textarea is focused:
- Arrow Up/Down — reads historical user messages from the live
ConversationSnapshotand fills the composer viainputActions.setDraft(). - Ctrl+C — calls
setDraft('')when the input is non-empty and nothing is selected.
No host process code, no persistence, no settings — pure client-side, stops cleanly on plugin stop/update.

🤝 Contributing
PRs are welcome! Please make sure the plugin still works in the DSH Web GUI after
your change. Keep the client code plain-JavaScript (no TypeScript/JSX in the shipped
lib/ output) and never add host-side logic unless the feature truly needs it.
