Is it possible for the newer ESS's to be programmed so that the `*' key
on the telephone could be used as a single digit backspace?  I think that
it's high time the telephone companies provide such a feature given the
extended dialing sequences (sometimes) needed nowadays.  It's frustrating
to have to hang up after dialing "n" digits...I'd much rather...

	Press:	1-617-555-123		Say: Blast!  I meant "1"!
	Press:	*12

...and complete my call to 1-617-555-1212.  Multiple presses of `*' ought
to have the expected result, of course.

Note:
	a)  I have never subscribed to any of the features offered by
	    the operating companies (call waiting, etc.), so forgive my
	    ignorance if the `*' is already spoken for.
	b)  I imagine that some telephone manufacturers have implemented
	    local backspace, kill and other canonical input processing,
	    but I'm more interested in an operating company solution since
	    I would also like to use this feature at a friend's home.
