Trapping focus in a modal merely means that pressing the tab/arrow keys will cycle you through the modal elements until the modal is dismissed. It is not a keyboard trap in the sense that it is an unescapable dead end.

Actually keyboard traps are a WCAG violation and should never happen
Snippet: 2.1.2 No Keyboard Trap: If keyboard focus can be moved to a component of the page using a keyboard interface, then focus can be moved away from that component using only a keyboard interface, 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. (Level A)

Hmm, trapping me inside a modal. I don't think I like the approach Ramakrishnan. The only way I would approve it is if I have a way of getting out.

Think of this.

You trap me inside the modal and I device to press Insert + 7 to pull the list of links on the page, because I decided to go somewhere else. What if JAWS cannot get out of this modal?

Can't you use proper semantic and put the cursor at the top of the modal and let the browser handle the tabindex and navigation?

Subject: [WebAIM] Keyboard trap for non-modal dialogs and popups:

Dear members
I request for your inputs on the following thing.

Is it a good practice to trap the keyboard focus inside the popup or a non-modal dialog?
I mean, while using arrow keys and tab/shift tab keys, trapping the focus inside the popup.
Generally the mouse user is able to access the parent page and also the popup simultaneously.
Should this be the case for the keyboard only users and screen reader users?
Which approach would be recommendable here?
What are the pros and cons for both the approaches?

Thanks for your inputs
Ramakrishnan
