Courtney,

My question then is more related to focus and user behavior. If the
new controls appear after a blur, you may have to do some JS focus
redirection, certainly if they are appearing outside of the
immediately contiguous tab order this is the case. If however, they
are appearing in the tab order immediately following the control, and
fast enough to be included when the user presses TAB, an alert may not
be necessary.

I'd have to have a better idea of the user behavior to answer it
better, but focus redirection may be a bigger help than an alert.
