Harry Loots wrote: “Probably no more so than clicking on multiple skip links, as you traverse header, main navigation, secondary navigation, etc, etc...” Sorry, I meant inefficient from a UA implementation point of view. If the objective is to move focus directly to the start of the main content, it seems that hooking into a specific element is a more efficient and reliable way to do it than by using a process of elimination. “The advantage of having such a technique, would be that a user can jump from one block of (non-interesting) content to a next block of content with a single shortcut key sequence. So that, even where developers have forgotten to mark up blocks of content, and have forgotten to provide skip links, users can still skip reasonably quickly to main content blocks.” We already have that ability (in screen readers at least). HTML5 elements and/or the ARIA landmark roles they map to facilitate movement between chunks of content using a single key command. One of the attractions of the main element is that it could facilitate a single command to move focus directly to the main content area of the page. Essentially like a skip link, but one that can be invoked from anywhere on the page not just when focus is on a particular anchor. This is already possible with role=”main” of course. The advantage of mapping the main role to an HTML5 element is that it becomes a native part of HTML, which increases the likelyhood it’ll be used. So whether you move from one chunk of content to another and finally arrive at the main content, or want to move directly to the main content area, hooking that interaction into a specific element would seem to be the most sensible way to approach it.

However, it's worth considering the principle Ian promotes: That the UA ignores (the way I understand what he proposes) <header><nav><footer><aside><etc> and lands on <main>, e.g., (my understanding/interpretation) by using a built-in short-cut key exposed to all users.

We have mapping of landmarks built in to HTML structural elements (in various stages of implementation) We have evidence to suggest that authors understand how to implement landmarks. Then we have a thought experiment from hixie that says hey you don't need those landmarks especially role=main. This idea has been brought up over and over by Hixie (note it was rejected on his home turf at the WHATWG) and never gained any traction, browser implementers rejected it in favour of adding the <main> element ( a number of whom have already implemented it). So we now have a method that works (is supported out of the box by AT) and work is also happening to build upon it to provide a simple browser built in skip to content feature that any user can make use of, so in time the necessity of providing a skip link will diminish. It would therefore seem more productive to be debating other topics. with regards -- SteveF HTML 5.1 <http://www.w3.org/html/wg/drafts/html/master/> On 27 March 2013 08:50, Léonie Watson <tink@tink.co.uk> wrote: Ian Hickson wrote: "In the interface I am proposing, there is no repeated questioning.

It's more reliable and less process intensive to move from A to Z, than it is to move from A, to B, to C, to D and so on until all that remains by a process of elimination is Z. So if the goal is to have a single mechanism for moving directly to a given point on the page, what's the hook the UA uses to make that possible?

In the interface I am proposing, there is no repeated questioning. The user indicates to the software that the user wishes to skip uninteresting content and jump to interesting content, in a single action (exactly the same kind of action as is used to jump to a header, or to jump to a specific landmark role).
