Re: Keyboard trap for non-modal dialogs and popups:

WAI-ARIA authoring practices dictate that 'focus must be held within the dialog until it is cancelled or submitted- (http://www.w3.org/TR/wai-aria-practices-1.1/#dialog_modal). Note: This is for modal dialogs. Non-modal dialogs should not trap focus and should be able to be dismissed appropriately (see Jonathan's response related to the F6 key and Brian's the escape key).

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)
