Have you noticed on Google?

I've been using Google since it first hit the scene and they just keep improving it. Just now I finally realized that they even give you search tips with your results. The one I just got was:

Tip: In most browsers you can just hit the return key instead of clicking on the search button.

Yeah, most people already know it, but I see so many people who don't, and they could save themselves probably 15-30 minutes each week using that tidbit instead of stopping, grabbing for the mouse, and then hunting for the button.

Now, if they'd just make these more prominent, and maybe cook up a few dozen of them to get more rotation, people might really get streamlined.
