Lag between pressing down arrow and highlighting the next control in Quick Add causes wrong control to be selected

When I search for "text", I often actually want the Text Input control (second on the list), so I hit the down arrow followed by return. If I type these two keys quickly enough, I get the Text Area control instead (first on the list).

I'm guessing this might have something to do with the animation it does when you hit the down arrow since I'm not exactly on the world's fastest PC - a 1.7 GHz Pentium M running Windows XP.
