# alertShowHelp(_:)

Sent to the delegate when the user clicks the alert’s help button. The delegate causes help to be displayed for an alert, directly or indirectly.

```
@MainActor optional func alertShowHelp(_ alert: NSAlert) -> Bool
```

## Return Value

<doc://com.apple.documentation/documentation/Swift/true> when the delegate displayed help directly, <doc://com.apple.documentation/documentation/Swift/false> otherwise. When <doc://com.apple.documentation/documentation/Swift/false> and the alert has a help anchor ([`helpAnchor`](/documentation/AppKit/NSAlert/helpAnchor)), the application’s help manager displays help using the help anchor.

## Discussion

The delegate implements this method only to override the help-anchor lookup behavior.

## See Also

[`var showsHelp: Bool`](/documentation/AppKit/NSAlert/showsHelp)
