• Syntax highlighting: Built-in language support for many formats (C/C++, HTML, CSS, JavaScript, Python, XML, INI, etc.) with customizable styles.
• Code folding & line numbering: Helps navigate and manage large files with collapsible code blocks and persistent line numbers.
• Search & replace (Regex): Powerful find/replace with regular expressions, incremental search, and whole-word/selection-only options.

• Auto-completion & brace matching: Basic auto-complete, keyword highlighting, and bracket/brace matching for coding efficiency.
• Bookmarking & markers: Set bookmarks and markers to quickly jump between important lines.
• Session & workspace restore: Keeps recent files and can restore sessions so you pick up where you left off.
• Portable settings sync: Use a config file stored with the executable to keep preferences across machines.
• Printing & print preview: Lightweight printing support with configurable headers/footers and print preview.
• Plugins & external tools: Integrate external tools or scripts via command-line parameters or custom menu entries.
• Hex view & binary-safe editing: Open and view files in binary or hex when needed.
• Quick file compare (diff) support: Integration hooks for external diff tools to compare files rapidly.

Power-User Tips

1. Make it truly portable: Store Notepad3.exe and the Notepad3.ini in the same folder (e.g., USB) so all settings travel with the app.
2. Custom language styles: Edit the style configuration to set fonts, colors, and keywords that match your favorite theme.
3. Use project-specific configs: Keep different INI copies per project folder for workspace-specific settings.
4. Map external tools: Add compiler/run scripts to the toolbar or menu so you can build/test files directly from the editor.
5. Leverage regex search: Save frequent regex patterns in a quick-reference file to speed up complex replacements.
6. Backup settings: Periodically copy your INI to cloud storage to preserve customized shortcuts and styles.

When to Choose Notepad3 Portable

• You need a no-install, fast editor for occasional coding or text tweaks.
• You want a lean alternative to full IDEs with essential coding aids.
• You work across multiple PCs or carry tools on a USB stick.

Limitations to Consider

• Not a full IDE — lacks advanced debugging, refactoring, or project management features.
• Plugin ecosystem is limited compared with editors like VS Code or Notepad++.
• Some advanced language-aware features (IDE-level auto-complete, linting) are minimal or require external tools.
