This technique requires a handshake.  The browser cannot do it
without some cooperation from the AT and vice versa.

	How about: Give the user {quiet, alert, confirm} options
	governing script execution

	This blends into the above technique.  What matters is the
	impact of the script.  If the user wants to review/confirm
	prior to letting the script execute, it has to be caught
	prior to execution.  How to communicate what will happen
	is tougher.  On alert to offer the option of communicating
	what changed is easier.  There are plenty of tricks of the
	trade such as a transient select on the least document
	subtree enclosing the change.

	This is extending the "confirm" meta-control to all
	new-window transactions.

This has to do with the assumed state model.  Is there a
cross-platform definition of select, focus, etc. that we can
build on?

"Current table" probably combines some of the characteristics
of "select" and "system caret."  Need to worry about whether
the state of the tabbing cycle moves, too.  Likewise for
table cells.  Need to define the "current" state operationally.
