|
|
```tsx
|
|
export function CommandMenu() {
|
|
const [open, setOpen] = React.useState(false)
|
|
|
|
React.useEffect(() => {
|
|
const down = (e: KeyboardEvent) => {
|
|
if (e.key === "k" && (e.metaKey || e.ctrlKey)) {
|
|
e.preventDefault()
|
|
setOpen((open) => !open)
|
|
}
|
|
}
|
|
document.addEventListener("keydown", down)
|
|
return () => document.removeEventListener("keydown", down)
|
|
}, [])
|
|
|
|
return (
|
|
<CommandDialog open={open} onOpenChange={setOpen}>
|
|
<CommandInput placeholder="Type a command or search..." />
|
|
<CommandList>
|

<CommandEmpty>No results found.</CommandEmpty>
