Yes, a very good solution for ttabs, David. aria-controls can be used of course (e. g. Jaws has shortcut keys to move focus). Do you have any examples of exactly this implementation?

I've not tested tabs very carefully with users, but a small observation: most users tend to use Enter and Space as similar keys in web interfaces. This works for buttons, checkboxes etc. Therefore it may be a little bit confusing that these keys have different behaviour in tablists. But of course, it is possible to learn this.

Emne: RE: Tab Panel focus movement with Dynamic content.

Sean, I tend to recommend:

  1.  Pressing Left/Right arrow keys in the Tab List moves focus between the items without selecting.
  2.  Pressing Spacebar on a Tab List item, selects the item but does not move the focus, and an aria-alert reads the Tab Panel heading as it changes.
  3.  Pressing Enter key in the Tab List selects the item, moves focus to the Tab Panel heading and reads it.
  4.  Pressing Tab key in the Tab List moves focus to the Tab Panel heading and reads it.

Subject: Tab Panel focus movement with Dynamic content.


What is the best practise if a web page has a tab panel and the content dynamically updates after the tab is selected?

1.      Should the focus move to the first focusable element?

2.      The focus does not move, leaving it up to the user?
This brings up another question. When should the focus automatically move to the first focusable element, other than dialogs/pop-ups when dealing with dynamic content?
