# setHelpAnchor(_:)

Sets the help anchor string for the sheet or modal panel.

```
func setHelpAnchor(_ anchor: String!)
```

## Parameters

`anchor`

The new help anchor string.

## Discussion

You may call this function to set a help anchor string if you display a help button in the sheet or modal panel and do not implement the delegate method <doc://com.apple.documentation/documentation/ObjectiveC/NSObject-swift.class/certificatePanelShowHelp(_:)>, or if the delegate method returns <doc://com.apple.documentation/documentation/Swift/false>. If you display a help button, do not set a help anchor string, and do not implement a delegate, the certificate panel displays a default help page (“What is a digital identity?”).
