dsh-find-bar

English | 中文

A web plugin for DeepSeek Harness (DSH) that brings back ⌘F / Ctrl+F in-page find for the desktop Electron shell, which ships without one. Browser-grade find bar: highlight-all, match counter, Enter/Shift+Enter navigation — plus a centre｜right scope picker so the conversation and the right extension panel are searched separately instead of as one page.

Search scope

The segmented picker overlays the input's right side and maps to the app's two searchable columns (the choice is remembered across opens). It never resizes the bar: with the right column collapsed the pills simply vanish. The segments are text-free pills — left pill = conversation (default), right pill = right extension panel — and hovering the picker shows one shared hint bubble styled after the app's own control tooltips (500 ms delay, theme-matched surface).

Scope rules:

• The picker only appears when there is a choice: with the right column

collapsed, search runs on the conversation alone and the picker hides entirely — it reappears as soon as the column is opened. If the active scope collapses mid-search, it falls back to the conversation without overwriting the saved choice.

• Folded regions are skipped: auto-folded tool steps and hidden panes do

not match; expanding a region re-counts its matches within ~250 ms.

• A fullscreen right panel (covering the centre) still counts as "R".
• The left sidebar is not a scope: the dsh workspace already searches it.

How it works

Electron has no built-in find bar. This plugin implements one client-side:

• Listens for ⌘F/Ctrl+F (capture phase) and draws a themed find bar.
• Collects text nodes with a TreeWalker (shadow roots included), rooted at the

selected column (the right column carries the stable [data-rightbar-col] anchor; the centre column is its previous sibling), and drops matches hidden by collapsed regions (checkVisibility).

• Highlights via the CSS Custom Highlight API (CSS.highlights +

::highlight()) — paint-only, zero DOM mutation, zero React conflicts.

• A MutationObserver (including attribute changes) re-scans on a debounce as

content streams in and regions fold or expand.

• Environments without the Highlight API fall back to window.find()

(no scope or counting in that mode).

Keyboard

Key · Action ⌘F / Ctrl+F · Open the bar (prefilled with the page selection) Enter / Shift+Enter · Next / previous match ⌘G / F3 (+Shift) · Next / previous Esc · Close and clear highlights

Search-as-you-type (debounced, follows streaming updates); the counter shows current/total.

Install

dsh plugin --profile <profile> add dsh-find-bar

Installs from npm (recommended); or from source:

git clone https://github.com/secyborg/dsh-find-bar
dsh plugin --profile <profile> add ./dsh-find-bar

Restart the app once after installing (plugin manifests load at startup).

Known limitations

• Only searches text rendered and visible in the DOM; collapsed sessions

or long lists must be expanded first.

• Web content inside panel iframes is out of scope.
• Match cap of 5000 (shown with a + suffix).
• Case-insensitive; no "match case" toggle yet.
• The window.find() fallback mode has no scope picker.

Uninstall

dsh plugin --profile <profile> remove dsh-find-bar
