Ctrl + Wheel Zoom

Hold Ctrl (or ⌘ on macOS) and scroll the mouse wheel to zoom the whole DeepSeek Harness Web UI. A small chip at the frame's bottom-right corner reports the current level and returns to 100% in one click.

Features

Gesture	Result
Ctrl / ⌘ + wheel	Zoom in/out in 10% steps, 50%–200%
Ctrl / ⌘ + + / -	Same from the keyboard
Ctrl / ⌘ + 0	Reset to 100%
Bottom-right chip	− / + step the level; clicking the percentage resets

The level is remembered in the browser (localStorage) and restored on the next page load. The chip appears only while the level is not 100%, so the frame stays untouched in the default state.

Install

This is an ordinary DSH profile bundle: plain ESM, no build step, no runtime dependencies. It is published on npm as dsh-ctrl-zoom and can also be installed straight from GitHub.

From npm (recommended)

1. Open Plugins in the DSH sidebar.

2. Choose Add plugin, enter the package name, and install:

   dsh-ctrl-zoom
   

   Or ask the Harness agent:

   plugin_manager  action: install_bundle
                   target: dsh-ctrl-zoom
   

3. If the Web UI was already open, refresh the page once (Ctrl/⌘ + R).

From GitHub

From a local checkout

git clone https://github.com/jinmuxi1/dsh-ctrl-zoom.git

Then ask the Harness agent:

plugin_manager  action: install_bundle
                target: <absolute path to the cloned directory>

From a tarball

npm pack

plugin_manager  action: install_bundle
                target: <absolute path to dsh-ctrl-zoom-1.0.0.tgz>

Migrating from dsh-ctrl-wheel-zoom

If you previously installed the older dsh-ctrl-wheel-zoom bundle, remove it first:

plugin_manager  action: remove_bundle
                target: dsh-ctrl-wheel-zoom

That bundle registers its client module under a different id than its package name, so enabling it fails the Web boot. This package is the maintained replacement.

Uninstall

plugin_manager  action: remove_bundle
                target: dsh-ctrl-zoom

Compatibility

• Tested with DeepSeek Harness 0.2.1-rc.2 Web GUI (Electron 44).
• The client half needs a Chromium-based Harness shell. In a non-browser Host it is inert.
• No Node dependencies and no install scripts.

How it works

Zoom is CSS zoom on <html>. It scales layout, text and fixed overlay layers together like browser page zoom, while the app's own scroll containers keep working. A transform: scale() wrapper cannot scroll its oversized content, and a font-size change would only touch text.

The wheel listener runs in the capture phase on window and calls preventDefault(), so it sees the gesture before app scroll containers and the browser's native page zoom does not apply a second, independent level. A gesture another component has already handled (event.defaultPrevented, for example an embedded editor or map with its own Ctrl+wheel zoom) is never stolen.

Everything is registered through ctx.effect: unloading the plugin removes the chip entry, both listeners, the stylesheet and the applied zoom property.

Privacy

The plugin makes no network requests. It reads and writes one localStorage key for the zoom level and applies a CSS zoom value to the document element.

Development

Requires Node.js 22 or newer.

npm run check

check runs node --check on both halves and validates the manifest, locale metadata, patch reference and the client module id. GitHub Actions runs the same command on every push and pull request.

中文说明

按住 Ctrl（macOS 也可用 ⌘）滚动鼠标滚轮，即可缩放整个 Harness Web 界面：范围 50%–200%，每格 10%。Ctrl + + / - 也能缩放，Ctrl + 0 恢复 100%；右下角比例胶囊支持 − / 点击百分比重置 / +。比例保存在浏览器 localStorage，下次打开页面会自动恢复。

安装：让 Harness 的 Agent 执行 plugin_manager action: install_bundle target: <本目录绝对路径>； 如果页面已经打开，刷新一次即可。卸载： plugin_manager action: remove_bundle target: dsh-ctrl-zoom。
