Why jano?

• Shortcuts you already know — Ctrl+S, Ctrl+Z, Ctrl+C/V, Ctrl+A. No modes, no .vimrc.
• Multi-cursor that actually works — Ctrl+Shift+Up/Down to stack, Ctrl+D for next occurrence, autocomplete inserts at every cursor.
• Full mouse support — click, double/triple-click, drag-select, scroll, auto-scroll at edges.
• Autocomplete with popup — plugin-driven completions + buffer words.
• Inline validation — errors and warnings from plugins appear right next to the line, F4 for details.
• Auto-formatting — F3 runs the active plugin's formatter on the whole document.
• Plugin store — jano plugin install yaml, browse at janoeditor.dev/plugins.
• Zero bloat — ~59KB JS bundle, starts instantly, smooth scrolling at 60,000+ lines.
• 100% JavaScript — no native addons, no compile steps. If you can read JS, you can extend jano.

Plugins

Plugins add syntax highlighting, formatting, validation, and completions for any file format. A plugin is a single TypeScript file — if you can write a regex, you can build one.

Ready-made plugins: YAML, JSON, Markdown, Shell, Dockerfile.

Build your own: see the docs or check out plugin-yaml as a reference.
