In its latest update, Google Operating System blog noticed that some of the One line Sitelinks are now supporting links within the same page, that points the searcher down to a portion of the same page. That means Google Sitelinks are now Supporting HTML Anchor texts. For instance, a search for [Raja Ravi Varma] in Google returns a Wikipedia result at the top. The result has the classic one line Sitelinks, but instead of the Sitelinks hyperlinking to different pages, they hyperlink to the same page, but point down to the page to a specific section.
Normally, Google's "One Line" Sitelinks points links to different web pages within a website. For instance, Search engine query on Google Search shows one line sitelinks for top two results (Dogpile and Altavista), pointing to different pages within those websites.
IMO, Yahoo’s quick links have been doing this for a while now. But, search for [Raja Ravi Varma], Yahoo takes the different set of Anchor texts within the page when compared to the Google Search Engine.
To sum-up the topic, one line site links is not new, but the anchors feature seems to be new from a Google search page perspective.
