Finding Stuff Inside Windows

Sometimes I overlook the most blatantly simple stuff.  Case in point is reading the instruction manual that explains features on my fancy mice.  I'm on the computer constantly and use a different mouse in each hand to reduce repetitive stress and speed up my navigation.

But sometimes I forget that you can also get to the top of bottom of a long windows page by clicking in the empty space between the "elevator bar" and either the up or down arrow.  Boom, fast way to scroll to the bottom of the page.
