Here the user is pressing his finger down on the period (".") key. Five choices pop up, and one in fact is then filled in for him in the above URL line.
But what if he doesn't want any of these choices?
Well the moment he releases his finger the menu goes away and the ".com" is left there in the URL bar for him to clean up on his own.
Sure you might say, "No big deal. Cleaning up three letters and a dot just takes a second."
Okay, but it could have been a much longer string. And it might have been "Choose your life insurance plan."
I am asking: is there ever any justification, for omitting a simple additional "X" choice that will get the user back to the previous step?
