I think if you type the application name the expected behaviour would be to just hit Return to launch it.
But you are right, as far as I remember the search results take over the screen and appear from top to bottom. But I fear you cannot really cater for people who click a button, then start typing and then click again – all of which would be done on the keyboard instead of constantly switching.
Or maybe they need it for gathering thoughts. The time required to switch input devices may come close to the time required to formulate in one's head what is it actually what one is looking for. But that is pretty much speculation ;-)
