This evidence comes from the upstream catalog. This site has not installed, run, or security-reviewed the plugin.

Install

Start with a prompt that asks an agent to review the GitHub repository and source. Switch to the command if you want to install it yourself.

Copy this prompt into DSH, Codex, or another agent and ask it to review the GitHub repository and source first.

Do not install or run any commands yet. Read this plugin's GitHub repository, README, and relevant source code. Then answer the questions below clearly and directly so I can decide whether it fits my needs:

1. What is this plugin, and what problem does it solve?
2. Who is it for, and what are its typical use cases?
3. How is it used after installation? Include one minimal example.
4. What known limitations or privacy, security, compatibility, or maintenance risks does it have?
5. Give a clear recommendation: recommend, conditionally recommend, or do not recommend, with reasons.

Distinguish statements documented by the repository, inferences from source code, and unknowns. If evidence is insufficient, say so explicitly. Do not guess or simply repeat the README.

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+C stays the system Copy).

🧩 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

ConversationSnapshot and fills the composer via inputActions.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.
