< moved from another location > I've just experienced a floating text window with a Google logo inside my browser window, appearing over a retrieved page and guiding me to the most appropriate section of the page. Somewhat similar to the New York Times floating links to related articles I've seen in the bottom right corners of a Times page when I scrolled down far enough, except in this case I didn't scroll down... it was there when the page loaded... and it further focused the Google query.
I searched for [keyword define], and Google returned a normal looking set of results, with no jump to or direct nav links within the snippets. On the returned page of the second result I tried, though, in the lower right hand corner of my browser window, was a small floating window with a Google logo followed by a headline...

This was then followed by a sentence of about 25 words on 3 lines in which
keyword definition was included...
Inline with the sentence, immediately after it, was a text link:
Jump to text >> Clicking the link took me to a line of text, the start of the sentence highlighted in light blue, 8 paragraphs into a 10 paragraph page.
While "jump to" Fragment Identifiers, inline mini-sitelinks, and rich snippet direct navigation links have been reported to appear in Google snippets, this doesn't appear to be related to any of these, in that there's no special markup on the page. The source code is a straight <p> paragraph, no special identifier of any guide. This was a relatively long page, but in the past it's taken markup of some kind to trigger a deep link in the snippet.
PS: levo - Thanks for the alert that you'd posted about this earlier. This new feature didn't get much attention.
I was impressed that Google was able to dig out the particularly relevant section deep in the page and to take me to it without special markup. I think that Google's interface always provides clues about its indexing capabilities, so I feel it's worth a note.
