Copy & Paste Library Items and Powerful HTML Search Improvements Arrive in HelpNDoc 10.4

We’re thrilled to announce the release of HelpNDoc 10.4! This productivity-focused update introduces long-awaited workflow enhancements, significant improvements to the built-in HTML search engine, and a variety of refinements across the application. From the new ability to copy and paste library items across projects, to faster and more consistent end-user search results, improved documentation output, and numerous UI and editor fixes, this version delivers meaningful gains for technical writers working on projects of all sizes.

As always, HelpNDoc is free for personal use and evaluation, so now is the perfect time to download the latest version and experience these enhancements for yourself.

📚 Copy and Paste Library Items Across and Within Projects for Faster Content Reuse

HelpNDoc 10.4 finally introduces powerful copy-and-paste operations for library items, making content reuse faster, safer, and dramatically more flexible.

Library items are at the heart of how HelpNDoc helps you maintain consistent, reusable content. They include all shared media and dynamic elements such as pictures, documents, snippets, dynamic content, equations, image maps, videos, barcodes, raw HTML blocks, variables, counters, and organizational folders. Once placed in topics, library items are centrally managed. Update them once, and they’re updated everywhere they’re used.

Previously, library items could be imported from other projects, but they could not be directly copied and pasted. HelpNDoc 10.4 removes this limitation entirely.

You can now copy and paste individual library items, multiple selected items, or entire folders recursively, including all nested content. These operations work seamlessly both within the same project and across different projects, making it easy to reuse approved media, share standardized snippets, and migrate content without duplication.

Behind the scenes, HelpNDoc uses highly optimized algorithms designed to handle very large libraries efficiently. Even complex, asset-heavy projects benefit from excellent performance, ensuring that copying and pasting remains fast and reliable regardless of scale.

🔍 A Much Smarter and Faster Built-In HTML Search Engine for End-User Documentation

The default HTML documentation template now features a significantly more powerful, faster, and more consistent search engine, while remaining lightweight and fully client-side.

HelpNDoc’s HTML output has always included a custom JavaScript search engine designed to be extremely fast and compact, running entirely in the end user’s browser without relying on server-side technology. This approach keeps downloads small and ensures excellent performance, even on limited hardware.

With HelpNDoc 10.4, that search engine takes a major step forward. It now supports true AND searches by allowing required terms to be prefixed with a plus sign, and it introduces exact full-word matching using quoted phrases. An optional template setting also enables accent-insensitive searches, allowing users to find accented words even when entering unaccented queries.

Performance has been significantly improved thanks to internal preprocessing and scoring optimizations, making repeated and complex searches noticeably faster. Repeated required terms are now handled correctly and behave predictably. Search results with identical scores are displayed in a stable, consistent order across runs. Numerous edge-case filtering and exclusion bugs have also been resolved.

These improvements make the built-in HTML search far more powerful and reliable for real-world documentation, while preserving its key advantages: lightweight delivery, offline usability, and effortless deployment.

🌐 Improved HTML and Markdown Documentation Generation with Better Accessibility and Reliability

HelpNDoc 10.4 improves the quality of documentation output with accessibility enhancements, usability fixes, and safer HTML generation, and a key Markdown correction.

HTML documentation generation has received several important upgrades in this release, particularly around accessibility and usability. Keyboard navigation has been refined throughout the interface, including smoother navigation within tree controls and clearer focus behavior. Screen-reader support has been improved, and when users navigate search results via the keyboard, the first valid result now receives focus correctly.

These enhancements make generated documentation easier to use for people with disabilities and also contribute positively to SEO, helping HTML output perform better in search engines such as Google. At the same time, the underlying JavaScript library used by the default HTML template has been strengthened to safely handle edge cases in both default and custom templates, preventing interface malfunctions for end users.

Additionally, Markdown generation has been updated so that topics marked as hidden in the table of contents are excluded from exported Markdown tables of contents. This ensures that the exported structure accurately reflects the project’s visibility settings.

🧭 UI Enhancements, Equation Editor Improvements, and Important Bug Fixes

HelpNDoc 10.4 delivers a variety of quality-of-life UI improvements, upgrades to the equation editor, and fixes to improve the robustness of the application.

Several everyday workflows have been refined to make authoring faster and clearer. The auto-completion dialog used to insert hyperlinks to other topics now displays breadcrumb hierarchy hints when hovering over topics, making it easier to distinguish between items with identical or similar names. Reference library items have also been improved: hovering over them now displays the user-defined output formats for both HTML- and report-based documentation, providing immediate feedback on how references will render.

The built-in equation editor has been significantly upgraded, offering faster performance, enhanced accessibility, and a more robust LaTeX and scientific notation parser with automatic formatting. Numerous bugs in the editor have been fixed as part of this update.

Beyond editing tools, HelpNDoc 10.4 improves overall robustness by correcting the behavior of open and save file dialogs, which could previously trigger access violation errors on some systems. The topic editor’s hint system has also been fixed to better handle edge cases where hints could appear without content.
