# Command palette
One search for every place and action of an app, opened from anywhere by `⌘K` or `Ctrl K`: a dialog with the combobox's search and a list of links and buttons - Enter opens a page by its plain link or runs a button's command.
## Example
The button opens the dialog by the browser's command and names its keys in `aria-keyshortcuts`, which the library also takes as the shortcut. The options are links and buttons with `role="option"`, in groups; the search finds them by their words and by `data-keywords`.

## Shortcuts
A button or a link whose `aria-keyshortcuts` names a combination with `Control`, `Meta` or `Alt` is pressed by it: the page states the keys once, for screen readers and for the library. Where both `Meta+K` and `Control+K` are named, Apple's systems answer `⌘K` and the others `Ctrl K`, so `Control K` keeps its meaning in a Mac's text fields; Firefox's own `Ctrl K` gives way to the page's.
- A single key is never a shortcut here: WCAG 2.1.4 asks for a way to turn such keys off, and a combination needs none.
- A disabled or hidden button is left alone, and so is one outside an open modal dialog.
- The hint the button shows - `⌘K` or `Ctrl K` - is the page's to write.
## Keyboard and accessibility
| Key | In the palette |
| --- | --- |
| `⌘K`, `Ctrl K` | Opens it from anywhere, the focus in its search |
| `↓` / `↑` | The next / the previous option, round the ends |
| `Page Down` / `Page Up` | Ten options on / back |
| `Enter` | Opens the active link or presses the active button; the palette closes |
| `Esc` | Empties the search; on an empty search, closes the palette, the focus back where it was |
- The palette is a modal `
