Hi all

Seeing you're all so good at answering questions, I'm wondering when something is truly a keyboard trap - the definitions seem to vary a lot.

2.1.2. states that if the keyboard focus can be moved to a component of the page, then you need to be able to move that focus away from that component solely by the keyboard as well.  and "If it requires more than unmodified arrow or tab keys or other standard exit methods, the user is advised of the method for moving focus away".

My question involves what "standard exit methods" this assumes.

Pop-up windows open in a variety of ways - new windows, new tabs.  Media players pop up from links and then the user has trouble closing them (if they even know they are in a new window).  Sometimes you can get out by Ctrl+W, or Alt+F4, and sometimes trying one of these causes lots of other problems.  It also depends upon what browser you're using.  For example in IE9, both Ctrl+W and Alt+F4 do the same thing, while in Firefox Alt+F4 displays a warningsaying do you want to close all tabs.  Also, sometimes closing the popup by a keyboard shortcut may close the browser which is a huge problem.

How do you decide what a "standard exit method" is?  There are quite a few lists, but many users aren't even aware of these shortcuts.  I'd personally like to see people provide an annoucement that the new window is opening and telling the user how to get back again, but I can't see that happening across the board.  For example, that's a lot of information to attach to a Twitter widget that's set to open a new window.

I appreciate your thoughts.

Tables of data; indices, references/ citations, lists, whole-year
calendars, etc.

For example, there are around 170 in the 'Notes' section of today's
"featured article" on the English-language Wikipedia:


 and far more than 200 in the whole article.
