A `helpAnchor` in AppKit is the name of an HTML anchor element:

AppKit > NSPrintPanel > helpAnchor
<https://developer.apple.com/reference/appkit/nsprintpanel/1490537-helpanchor>

AppKit > NSHelpManager > openHelpAnchor(_:inBook:)
<https://developer.apple.com/reference/appkit/nshelpmanager/1500908-openhelpanchor>

Apple Help Programming Guide > Authoring Apple Help > Indexing Your Help Book > Setting Anchors
