keywords "row" , "col", and "cell", for example: http://example.com/data.csv#row=4 – Selects the 4th row. http://example.com/data.csv#col=2 – Selects 2nd column. http://example.com/data.csv#row=5-7 – Selects three consecutive rows starting with 5th row. http://example.com/data.csv#row=5-* – Selects all rows starting with 5th row. http://example.com/data.csv#cell=4,1-6,2 – Selects a region that starts at the 4th row and the 1st column and ends at the 6th row and the 2nd column. In URIs for MIME audio/*, image/*, video/* documents, very few have defined fragments or fragment semantics. The Media Fragments URI 1.0 (basic) syntax supports addressing a media resource along two dimensions (temporal and spatial) using the keywords t and xywh. Therefore, one can use the following media fragments URI in the src attribute of the audio or video HTML5 element: http://example.com/foo.mp4#t=10,20 http://example.com/bar.webm#t=40,80&xywh=160,120,320,240 Other websites use the fragment part to pass some extra information to scripts running on them – for example, Google Video understands permalinks in the format of #01h25m30s to start playing at the specified position, and YouTube uses similar code such as #t=3m25s. In JavaScript, the fragment identifier of the current HTML or XHTML page can be accessed in the "hash" property location.hash – note that JavaScript can be also used with other document types. With the rise of AJAX, some websites use fragment identifiers to emulate the back button behavior of browsers for page changes that do not require a reload, or to emulate subpages. For example, Gmail uses a single URL for almost every interface – mail boxes, individual mails, search results, settings – the fragment is used to make these interfaces directly linkable. Adobe Flash websites can use the fragment part to inform the user about the state of the website or web application, and to facilitate deep linking, commonly with the help of the SWFAddress JavaScript library. A URI that links to a JSON document can specify a pointer to a specific value. For example, a URL ending in #/foo could be used to extract the value from a key-value pair in a document beginning with { "foo": ["bar", "baz"], ... } In URIs for MIME application/pdf documents PDF viewers recognize a number of fragment identifiers. For instance, a URL ending in .pdf#page=35 will cause most readers to open the PDF and scroll to page 35. Several other parameters are possible, including #nameddest= (similar to HTML anchors), #search="word1 word2", #zoom=, etc. Multiple parameters can be combined with ampersands: http://example.org/doc.pdf#view=fitb&nameddest=Chapter3.
