## What it does

- **Finds apps as you type**: whole names, starts of words, initials (`ss` is System Settings), letters in order, and typos (`chorme` is Chrome). What you open often climbs.
- **System Settings panes** (Mac): "login items", "wifi" or "dark mode" lists the pane, under the apps, and Return opens System Settings right at it.
- **Completes inline**: the rest of the top app's name, or of Google's top suggestion, is drawn faintly after the caret. Tab or → takes it; Return never does.
- **Does math**: `2^10 * 3` answers 3,072 (and `0xC00`). Return copies it.
- **Converts currency**: `100 USD to EUR` (or `100usd in sgd`) uses [Frankfurter](https://www.frankfurter.app)'s ECB daily rates. Return copies the amount. Offline or a failed fetch shows that the rates are away — never a made-up number.
- **Google suggestions**: up to four, under the apps, the words you add in bold. Nothing that reads as an address (a dot, a slash, an @) is sent.
- **Results in the panel**: Return on a search shows Google's page in the panel itself. Esc goes back to the list, ⌘↩ opens it in your browser, ⌘[ goes back a page. Prefer the browser? Turn on **Open Searches in Browser** in Settings: Return opens your browser, and ⌘↩ shows the page in the panel.
- **Ask Grok, search X**, a row away. **Ask Claude** too, once it's turned on in Settings.
- **Raycast extensions**: extensions from the [Raycast Store's repository](https://github.com/raycast/extensions) (MIT) run in the panel: their lists, details and forms, their actions on ⌘K. Choose **Install Raycast Extension…** to search the store. They are React and TypeScript, so they need [Node.js](https://nodejs.org) 20 or later on your computer; Nanolight brings none, and runs them through its own version of `@raycast/api` ([raycast/README.md](raycast/README.md)). AI, OAuth and the menu bar aren't supported.
- **Raycast script commands** ([raycast/s
