[Bug 13594] New: Handling of duplicate keyboard shortcuts


           Summary: Handling of duplicate keyboard shortcuts
           Product: HTML WG
           Version: unspecified
          Platform: All
        OS/Version: All
            Status: NEW

          Severity: normal
          Priority: P2

While we can and should define mechanisms to let dynamic content, add-ins and
the like negotiate to try to avoid conflicts, they may still occur at times.
With HTML4 and below, the behavior in such circumstances is left undefined, and
consequently is handled differently by different user agents and so cannot be
planned for. By contrast, native applications can count on specific, platform
behaviors; for example, on Windows if a menu has two items with the same
underlined accelerator key, the user knows that pressing the key will move the
focus sequentially between them, and they can activate the one with the focus
by pressing the Enter key. 

Issue: Should the author be able to suggest ways to handle shortcut conflicts?
If an author could specify that pressing a shortcut would move focus
sequentially between the elements that have that accesskey, and wrap, they
author could design keyboard UI to take advantage of this in a way that is not
otherwise possible. On the other hand, issues such as whether sequential
navigation wraps should ideally be under the user's control, since wrapping is
a significant advantage to some users (e.g. those who need to minimize the
number of input commands) but a disadvantage to others (such as those who may
not be able to tell when wrapping has occurred). Should the HTML5 spec state
instead that user agents should follow platform conventions?
