Web browsers should provide autocompletion for URL fragments for the current page.

Also, I should be able to address a fragment *just* by typing "#" + fragment_identifier, instead of current_url + "#" + fragment_identifier.

@colby Well, shouldn't the last one already work by just selecting the location bar, hitting right arrow if it selected the whole entry and then typing your fragment?

And yeah, given that most website hides the url fragments away, being able to get completion or just a page-sorted listing of them would be neat. *files a bug to get a proper API in WebKitGTK*
