Using rel="help"

The rel attribute defines the relationship between the current page and the linked page.

The rel="help" value indicates that the link offers context-sensitive help for the current page.

It can also mean that the help is for the parent element of the link with rel="help".

When used on <a> or <area> tags, the mouse pointer becomes a 'help' pointer (hand or question mark).
