[community] bookmarklet that presents lists of headings, links, aria landmarks

[Mark Weiler]

Does anyone know of bookmarklets that can do the following to a web page:
Extract and present a list of:
1. headings2. links3. aria landmarks
I know of bookmarklets that will annotated or highlight those areas in the rendered HTML but I would like to simulate a screen reader's "navigate a document by heading/links/aria landmark" feature. 

Thanks,
Mark
