Keyword Search: highlight and step through matches in long text — Tutorial

Upload an .md file (max 2MB) or click Import from clipboard to enter the pseudo-fullscreen preview workbench. Enter keywords to highlight matching sentences, jump between hits, and zoom the body. Nothing is uploaded to a server.

Features

• Dual entry (same pattern as JSON/HTML editors): upload Markdown on the left, clipboard import on the right; preview opens automatically—no separate Search click.
• Markdown is converted to readable plain text (strip #, table pipes, blockquote markers, etc.) for reading and sentence-level highlights.
• Multiple keywords separated by |; English matching is case-insensitive.
• Matching sentences: primary-colored keywords with underline; active sentence fully underlined; non-matches dimmed.
• Preview top bar: Reset, Paste upload, search field, match navigation (< current/total >), Line & paragraph settings.
• Zoom floater on the search row (right): 60%–400% (appears on pointer move, auto-hides after ~2s idle).

Use cases

• Find terms like “experience” or “metrics” in meeting notes
• Scan legal or product Markdown for clause keywords
• Paste long text, highlight by sentence, and review context match by match

How to use

1. Open Keyword Search.
2. Choose Click / drag to upload an .md / .markdown file (≤2MB), or Import from clipboard.
3. The preview workbench opens automatically; enter keywords in the top search field (separate multiple terms with |).
4. Use Previous / Next to move between match marks; zoom floater on the search row appears on move and auto-hides when idle (60%–400%).
5. Line & paragraph settings configure line/sentence/mixed-layout rules; the preview updates immediately after you confirm.
6. Reset clears everything and returns to the home cards.

Notes

• Runs entirely in the browser; nothing is uploaded.
• Markdown is shown as plain text after stripping syntax—not HTML rendering (needed for sentence-level highlights and navigation).
• Clipboard import requires HTTPS or localhost and clipboard permission.
• The site top bar is hidden in preview (keywordsearch-editing-lock), same as other tools’ editing lock.
