Automatic Language Detection
Open a .py, .java, .js or .xml file and Notepad++ colors it appropriately. The Language menu shows many supported languages, and highlighting follows the selected language.
Folding and Collapsing
Click the minus sign next to headings, braces or indentation blocks to collapse them. Ctrl+Alt+Right folds the current block; sweeping a big file this way makes structure visible.
Custom User Languages
Under Language > Define Your Language, you can define keywords, comments and operators for internal formats, persisted so your team's DSL gets color too.
Snippets
The Snippets plugin (via Plugins Admin) stores reusable code blocks you insert by a trigger word, handy for repeated boilerplate.
Key Points
- Language highlighting turns on automatically.
- Folding collapses code structure.
- User-defined languages cover custom formats.
- Snippets paste frequent patterns instantly.
