# Link

<!-- preview link 160 -->

`ui.Link` creates a text that opens a URL in the browser, or the app
registered for its scheme, when clicked, or with Enter while it has the
keyboard focus; Space scrolls the container around it, as in a web page.
It shows in the accent color, underlined while the pointer is over it, by a
line kept whole through descenders and slashes, where other underlines skip
their ink on macOS:

```go
ui.Link(c, "Privacy policy", "https://example.com/privacy")
```

## Paths in a router

In a page of a [router](https://mygo.egoist.dev/docs/ui/navigation.md), a path without a scheme, as
`/notes/42`, `edit` or `?tab=info`, goes there in the router, as `Push`
does, relative to the page shown as links in a web page are:

```go
ui.Link(c, "Next note", fmt.Sprint(id+1))
```

## Within a sentence

Inside a [rich text](https://mygo.egoist.dev/docs/ui/text.md#elements-within-a-sentence), a link is part of
the paragraph, wrapping with it; Tab reaches it all the same:

```go
ui.RichText(c).Children(func() {
	ui.Text(c, "Read ")
	ui.Link(c, "the guide", "https://example.com/guide")
	ui.Text(c, " to get started.")
})
```

Give it an empty label and `Children` to style parts of its text.

## Other actions

A link that does something in the app rather than opening a URL is a text
that is clicked: give `Link` an empty URL and ask `Clicked`, or use a
[button](https://mygo.egoist.dev/docs/ui/button.md).

```go
if ui.Link(c, "Show details", "").Clicked() {
	app.details = true
}
```

## Accessibility

Assistive technology sees a link named by its text, which it follows as a
click does.
