By the time you're typing in the URI, you've mentally committed to 
initiating a login action. Doing something else with your hands 
(orienting a pointer on a web-button and clicking the mouse-button) 
doesn't really count as another cognitive action then; good luck 
training users to treat these as separate endeavors which require 
different analysis.

Of course, it *would* become useful if the URI was automatically 
filled in for you, but then you lose the typing action (lose one, 
gain one). I can see where the auto-complete feature would be 
desirable for SSO, but it's not a "convenience" I care for (in fact I 
find it bloody INconvenient, on par with Word's auto-correct of 
spelling and grammar - what appears on screen should be exactly what 
I'm typing).

I think users that know about keyboard shortcuts (aware they can just 
hit "return" after entering the data) will take care of it all from 
the keyboard, instead of interrupting their end of the process to 
move hand to mouse, move pointer on screen, and click.
